Ancient Hiking Shoes

One of the important plants one sees along the trails at Mesa Verde and elsewhere in the Four Corners is the Yucca Plant. Among the ancient products made from the Yucca are sandals. A few examples of this ancient footwear are exhibited in the regional museums.

The Trail Guide for the Nordenskiold Ruin No. 16 Trail on Wetherill Mesa at Mesa Verde has the most extensive description of the biology and uses of the Yucca plant, but that trail was burned so severely by recent forest fire that hardly anything is growing there. The Knife Edge Botany Trail that starts at the Morefield campground area and tours the north Mesa Verde escarpment doesn’t mention the Yucca plant. The Petroglyph Trail Guide discusses the Yucca at stop No. 30 on the return leg along the mesa top. It is also identified with markers in the area near the Chapin Mesa Museum overlooking Spruce Tree House.

The Yucca plant was used to make cord, ropes, belts, snares, blankets, and sandals. The fleshy leaves were harvested with a stone knife. Then the leaves were roasted and peeled to remove the outer plant tissues. Next, the fibers were separated by pounding the heated leaves, and these were twisted into strands. The Aztec Ruins Museum has a display showing how a bone tool was used to remove the fleshy pulp and expose the fibers inside. The display says individual strands were twisted clockwise and groups of strands twisted counter clockwise, probably one of your little known facts.

Shampoo was made by pounding the roots into soap. Foods and syrups were made from the Yuccas blossoms and large pod fruit. Blooms appear in May and June and are a favorite food of mule deer. The Yucca fruit is about two inches long and 0.5 inch in diameter with a cylindrical shape. It starts out green and ages to brown and then gray. The fruit is described as tasting like summer squash and the blossoms taste like lettuce. There are many species of Yucca and they hybridize making identification difficult. The Yucca has a relationship with a small white moth that both depend on for reproduction. I’ve noticed that in the burned area leading to the Cliff Palace Loop that the Yucca plants either survived or have grown back quickly. During the winter season, the only green in the area is the Yucca plant.
The Anasazi Heritage Center near Dolores, Colorado has a pair of Yucca sandals side by side. The example to the left appears thicker than the lightweight model to the right. I’ve been wondering how the Pueblo people coped with the heavy snow that is possible in the region, but apparently there was a variety of foot wear available. The Aztec Ruins museum has some examples of sandals also. The Heritage Center also has a dissecting microscope display featuring a comparison of the Yucca fiber side by side with cotton fiber.

Lowry Ruins in Winter

Lowry Ruins is one of the few easy to visit sites of Canyons of the Ancients National Monument in southwest Colorado. In the winter, the site can still be visited but bring your snowshoes.

County Road CC is cleared west of Pleasant View, Colorado but the driveway into the parking area and the trail to the ruins is not cleared of winter snows. It is about 0.25 miles of snow shoeing to get to the ruins area. Lowry Ruins sits on a slight hill top with views of the sage plain area surrounding and all of the regional mountain ranges are in clear view. During my visit, it looked like a snow mobile had made a visit but there were no foot prints around the ruins site since the heavy snows of about 10 days before. The snow at the site appeared to average about two feet of depth. On a 30 F degree sunny day the snow surface was crusty and I didn’t sink in except for a few spots.
The interpretive information at Ancestral Pueblo sites doesn’t say anything about how the residents here would deal with heavy snows. It looks like snow drifts could build up high enough to block the low level doorways. Many of these structures had openings in the roofs with ladders, but how would that work if there was three feet of snow around the opening. The farming areas are thought to have been worked with digging sticks, but I haven’t seen any mention of snow removal sticks. We mostly visit these sites in the warm months of the year and don’t consider the problems of winter survival. How many of these rooms were for storage of firewood and food for the times when conditions might be difficult for weeks.
The interpretive information at the site says that the Great Kiva at Lowry is considered to be a feature that drew residents to this site over several generations. It was a relatively early structure here, but there isn’t any comment as to why it was so attractive. The Lowry site is at a higher elevation than the pueblo sites in the Hovenweep area 20 miles to the south. The winter snows are deeper at Lowry and take longer to melt in the spring.
A large kiva like this seems to be a valuable feature for a community. It is big enough to accommodate a large group and has the earth contact and insulation features that might make a long winter more comfortable. I spent about 1:30 hours on this visit on a comfortable winter day. I read at the Anasazi Heritage Center that some of the building stones at Lowry have petroglyphs inscribed similar to several that were found at the Escalante Pueblo. I circled around the site three times looking for them but didn’t spot any this time.

Hovenweep Towers in Winter

The Little Ruin Canyon Trail is located at park headquarters for Hovenweep National Monument near the south Utah and Colorado state line. Most visitors arrive here during the mild portions of the year but the many mysterious towers can also be viewed during the snowy winters.The circular, square, and D shaped towers, like the Twin Towers, are mostly perched along the canyon rim. This area is one of the best ruins viewpoints in the Four Corners as there are 10 sites to see within the 2 mile loop. The Hovenweep area received about 4 inches of snow while nearby and higher elevation Mesa Verde received nearly 2 feet during the same period. The sidewalk leading to the trail head was cleared of snow but the trail itself required careful walking with a few icy spots. Temperatures since the snowfall have stayed mostly below freezing. During the mild seasons of the year we often forget how difficult survival in this region must have been.
The Hovenweep Castle is one of the most spectacular ruins in the region, a complex of two D shaped towers. The stone walls are two or three courses thick and dating of the wood used show a constructions date of 1277, a relatively late time in the history of this culture. The south facing canyon below the rim is cleared of snow while the north canyon rim still has a thick layer. The Hovenweep Castle overlooks the area where a spring provides water for the site. Large Hackberry Trees benefit from the moist conditions.
Tower Point sits at the junction of the two canyon heads and has a commanding view down the canyon toward Sleeping Ute Mountain. The function of towers is not well understood, but this one clearly looks like a lookout point. There is supposed to be a pictograph somewhere below Tower Point. The trail up the canyon bottom is normally closed to visitors but rangers may lead hikers occasionally during the summer, based on demand.
I spent about 2:00 hours walking along the rim here on a 28 F mid January day, about two weeks after the most recent snow. The roads were mostly clear leading from the Cortez, CO area, a few patches of ice in spots that were always shady. I didn’t attempt to cross the canyon at the east end of the trail, but did an out and back counter clockwise hike from the trail head around to the Twin Towers and back.

Pottery Shards on the Trail

On most of the hikes in the Canyons of the Ancients and other lightly visited areas pot shards will be visible. Sometimes hikers will make small displays of shards found. Studying these and other artifacts is encouraged but moving them from where they are found is usually discouraged. The Anasazi Heritage Center near Dolores, CO acts as the visitor center for Canyons of the Ancients and has some good displays of pottery with some interpretive information to help understand the styles that might be observed along the trails.

The last groups of people living in the Mesa Verde area made pottery that are now called McElmo Black on White and Mesa Verde Black on White. Both types are thicker with more elaborate decoration than earlier types. The McElmo type is most common between 1150 and 1200 AD. It shows bands of triangles, checkerboards, steps and hatched areas. Bowls are usually painted on the insides only. Looking at the examples in the Heritage Center, the McElmo Black on White had a more faded look to them. They are slightly older on average, but that may be a coincidence.
Mesa Verde Black on White is most common after 1200 AD. It has heavier designs with more black spaces, placed in segments. Bowls are decorated on both inside and outside. During this time pitchers became less common with mugs becoming more popular. No interpretation of the development of mugs over pitchers is offered, but that fact set off my imagination some. There seemed to be more examples of Mesa Verde Black on White in this collection. There is a good display of three mugs side by side.
The one of the left is notable as it features a T shape cut out in the handle, similar to some of the doorways and rock art found in the area. The doorways at the Escalante Ruin site on the hill above the museum are T shaped. Extra thirsty drinkers might like the double mug up above, though It seems like drinking from one side would cause spilling of the other side.

I’ve observed a lot of corrugated shards along the trails. Corrugated pots had indented coils covering most of the surface and were durable for cooking corn and beans. The Heritage Center has examples also of earlier Black on White styles are named the Cortez and Mancos. The Cortez style dates from 875 to 1050 AD and features interlocking scrolls, scalloped and ticked solids and fine lines. Also, string of pearls designs are found.
The Mancos style dates from 975 to 1150 and has triangles hanging from the bowl rims, vertical lines from the rim, and hatching with straight lines or squiggles. Without a lot of practice it might be hard to distinguish these styles from each other based on a single broken piece, but Black on White should be clear. In the museum there are also some examples of pottery with three or more colors called Polychrome and some Red and Orange colored pottery. The southeast Utah area was the center of Red Ware pottery and the examples found closer to Mesa Verde are thought to have been traded into the area.

I thought the most interesting pottery display in the Heritage Center was the side by side of two flute players. The bowl on the left is McElmo style and Mesa Verde Style is on the right. Flute players are often called Kokopellis but the interpretation is more complicated than the popular culture recognizes. I haven’t seen any flute player rock art in the Mesa Verde or Canyons of the Ancients area, though there are many to find in nearby Utah. The left side bowl is identified as being from the Knobby Knees Stockade, which I think is on Cajon Mesa in an area that was supposed to receive water from the McPhee Reservoir Project. It is somewhere in the vicinity of Lowry Pueblo. Many of the pots on display list the site where they were found, and some of these sites are within the Canyons of the Ancients and can be visited.

One area where there are numerous pot shards visible is in Ute Mountain Tribal Park, particularly in the Mancos Canyon portion of the full day tours. All visits to Ute Mountain Park are guided and visitation is light, so the shards have remained mostly in place. The guides don’t seem to object to the creation of small displays of interesting shards as others sometimes do. The Kiva Point short trail and the Red Pottery Village have an overwhelming number of pot shards to view.

Large But Obscure Ruins Sites

Yucca House is a strong contender for most obscure National Monument. This large ruins site rests in the level farming area between Mesa Verde and Ute Mountain in southwest Colorado. Several miles northwest of Yucca House is the lightly visited Goodman Point Unit of Hovenweep National Monument. Two more large but lightly visited sites are on Cannonball Mesa and in Woods Canyon, both parts of the relatively new Canyons of the Ancients National Monument.

Yucca House was accepted as a National Monument in 1919 and has remained unexcavated the whole time since then. For visitors, it is somewhat difficult to visit as it remains as large rubble mounds overgrown with greasewood without any development for visitors. The area surrounding the site today is used as agricultural land that looks like it might be more productive than the areas on top of Mesa Verde. The Yucca House site has obvious green marshy spots where springs still bubble to the surface. The setting is interesting as it rests in the shadow of Mesa Verde and may have been visible from the west rim area. Mesa Verde may appear as an island of cultural development, but the valley areas below were also populated in ancient times. There are isolated preserved sites in the areas away from Mesa Verde but modern development has mostly obscured the remains of that civilization.
The Sand Canyon area has well known trail system that leads to many small ruins sites. Goodman Canyon is the next canyon to the east. At the head of Goodman Canyon is a large ruins site that is one of the outlying Hovenweep National Monument sites. Like most of the canyon head locations there is a spring providing water. It was the first site to receive Federal protection when it was withdrawn from homesteading in 1889. There are no visitor facilities at the Goodman Point Unit and no signs pointing it out. For a visitor, there are some paths to follow and there is some current excavation with some peeks into trenches and piles of collected sandstone bricks. The short brochure says there are 42 different sites to find here.
On the southwest side of the Canyons of the Ancients Monument area is the large Cannonball Mesa site that seems to receive little attention for such a large site. It is relatively easy to hike to and has a number of still standing walls. The terrain has fewer trees than Mesa Verde and most of the rest of Canyons of the Ancients. Like Goodman Point, the site is at the head of a canyon with a water source trickling out of the canyon wall.


The Woods Canyon Pueblo site seems to have been chosen as an example of a canyon rim living site to develop into an educational unit for schools. I’ve described the hike to the site as the Gas Plant Trail South. It seemed to me that after studying the site in school, the students might want to actually see it, but it looks like a difficult location to bring a class of students. Logistics of visiting aside, the site is arrayed on a somewhat steep slope above a creek that has year round water and farm fields. Most of the structures are rubble piles with a few intact wall sections near the canyon rim. Most of the area is obscured somewhat by the Pinon and Juniper forest. There are some examples of the use of large boulders as foundations for perched buildings.

Horse Trails East of Sand Canyon

Along the south and east edge of Canyons of the Ancients National Monument near Cortez, CO, there are many rock alcoves visible from the County Road G where access is blocked by private property. The only access for hikers in this area is the Sand Canyon Trail. There are horse trails that lead to the area east of the main Sand Canyon Trail but for a hiker it is a fairly long trek.

The most distant Ancestral Pueblo ruins site that seems to still be in hiking range is located more or less behind the Kelly Place Bed and Breakfast, maybe 1.5 miles east of the Sand Canyon Trail Head. There are two possible routes to get to this relatively large site. The longer way is to follow the main Sand Canyon Trail about 3.3 miles to the small sign that says “Sand Canyon”, then turn east off the trail and follow the unmarked East Sand Canyon Trail past three side canyons until it intersects with the drill hole service road.
Follow the drill hole road past the Mad Dog Tower site a few hundred yards to a vague two track trail. Then continue east to the small pipe lines that shoot up to the top of the mesa. There is another horse trail a few hundred yards south along the pipelines that crosses the pipelines and leads another mile or so to this site. On a previous hike it took me 2:30 hours to get to Mad Dog Tower using the main trails and it is another 0:30 minutes to get to this eastern site. The 3:00 hours assumes that there is no stopping at the 20 or more ruins sites along the way.
An alternate way is the Mouth of Sand Canyon route that is shorter, but includes scrambling down and up the side canyons near the lower end of Sand Canyon. Climbing in and out of these side canyons is feasible, but the route isn’t marked. There is a good alcove site in the eastern side canyon with a lookout point ruin above the alcove. The upper end of the east side canyon is near the drill hole road and a few hundred yards south of the Mad Dog Tower. From the drill hole road, find the horse trails and continue east.

The horse trails that cross the area east of Mad Dog are well marked and look like they get a lot of use. The horses seem to have an access point in the private property that is not available to hikers. The main Sand Canyon Trail area is dominated by hikers and mountain bikers, but the eastern area is the domain of horse riders.
A few hundred yards south and east of Mad Dog Tower there is another circular structure that has a dead Juniper tree in the middle of it. I missed this site when I was hiking east from Mad Dog Tower on the previous hike. It is close to the horse trail but not very near the rock face where I was looking at the alcoves.

The horse trail passes around the upper end of a deep side canyon and several empty alcoves before arriving at the site. There is a trail up to the site on the left side that enters on the left end. It looks like there are remains of three separate structures with the largest at the right end. The large structure on the right still stands tall with details of the doorway construction still visible.
I followed the Mouth of Sand Canyon route both out and back and stopped at the mouth alcove ruins and the lookout ruin above it. With another short stop at the circular neighbor of Mad Dog Tower, it took me 3:00 hours to arrive at this site. My return hike without stops took 2:00 hours and my total hike was 5:15 hours for about 6.5 miles on a 55 F blue sky day in late November. I carried and drank two liters of water.

Sand Canyon Pueblo Neighbors

At the north trail head of the Sand Canyon Trail in Canyon of the Ancients in southwest Colorado, to the west side, there is the short interpretive trail to the mostly unexcavated and large Sand Canyon Pueblo. With about 420 rooms, 100 kivas and 14 towers it is larger than the spectacular Cliff Palace at nearby Mesa Verde.

There is also an unpublicized site on the east side of the canyon rim near the trail head that spills over the rim into some of the alcoves just below the rim. This site is only 100 yards or so off the trail but is not visible from the trail. It is fairly easy to hike over and view this site. These sites at the Sand Canyon trail head rest on the Dakota Sandstone layer. The structures on the rim mostly appear as rubble piles, similar to the Sand Canyon Pueblo. Below the rim, there are some alcove wall sections that are similar to the alcove sites at the lower end of Sand Canyon. I haven’t spotted any alcove structures below the rim at the main Sand Canyon Pueblo from the main interpretive trail.

The below the rim area can be reached from the main trail by descending about 10 feet, then turning off the trail and working your way east. There may be a few rock cairns to guide the way. The rubble pile ruins start to appear before reaching the alcove. Looking inside, there are some roof beams still in place. Just to the east of the alcove, there is a notch that allows passage to or from the rim.
The rim structures don’t seem to be as overgrown as the Sand Canyon Pueblo sites, fewer trees coming up through them. This is a smaller site and there is a definite gap between the east site and the main site. I noticed a small hiker’s collection of pot shards on display. There aren’t any interpretive signs at the east site and there isn’t a trail to follow, but the distance is short.
