Lucy’s Warbler Trail

The Lucy’s Warbler Trail is the route Colorado birdwatchers follow to the riparian habitat at the bottom of Yellowjacket Canyon on the south end of Canyons of the Ancients National Monument.

 The trail head is 20 miles west of Cortez, CO along County Road G, then 2.4 miles north on the BLM gravel road to a west turnoff. I started my hike as this junction, which is 0.9 miles past the turn off and trail head to the top of Cannonball Mesa and just past a small dry wash. Cannonball Mesa has a large ruins site about 2 miles down the trail.

Lucy’s Warbler is 4 inches long with a gray back and whitish breast. It has a chestnut rump patch, white eye ring and a chestnut patch on the crown. Its habitat is along desert streams with mesquite, willows, or cottonwoods. The Peterson Guide that I have shows summer range to be mostly in Arizona and southwest New Mexico with a small question mark in southwest Colorado.

It is about 1.5 miles of hiking from the trail head west down into the canyon bottom. As it descends the trail makes a hairpin turn back to the east. The stream banks have quite a few Cottonwoods and Tamarisk trees with sagebrush further up the banks. The terrain along the beginning of the trail is dry with scattered Utah Juniper trees, short grasses, and desert shrubs.

In late March there is a healthy flow in the stream. The trail crosses the stream and I stopped at the crossing. About 100 yards further upstream is the junction with Risley Canyon with Yellowjacket Canyon making a big counter clockwise bend at that point. Late March has a moderate temperature for hiking but is too early to see many birds. To the right along the trail it is possible to view Risley Canyon from the rim.
From the cliffs above the crossing point, a small grassy hill is mostly encircled by the winding stream. On the top of the hill it looks like there is a rubble pile ruins site. It looks like a good location with water, farm fields, and sunny exposure available.

I explored down canyon a short distance until arriving at the same dry wash that crosses the road near the trail head. Following back up the wash but staying close to the cliffs I spotted a small dry wall ruins site. This site was in a small alcove with southern exposure, overlooking the dry wash and sage brush fields below.

From the small ruins site I climbed to the rim and worked back over to the main trail and returned to the trail head. My total hike of about 4 miles took 2:30 hours on a 58 F degree late March sunny day.

Ancient Hiking Shoes and Yucca Plants

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 corrugated styles can vary with the curvature of the rim. A straight rim is called the Manccos Corrugated style and is dated from 930 to 1000 AD. Slightly curved rims dating from 1050 to 1300 are called the Dolores Corrugated. Sharply curved rims are from 1100 to 1300 and are identified as Mesa Verde Corrugated. 

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 Cahone 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.

A station in the museum has four dissecting microscopes set up with samples of pottery and other artifacts for a close examination. There are several boxes of samples to look at with interpretive information built into the samples. Very small signs are embedded in the sample cases to explain what you are looking at.

 It is a very creative exhibit and I haven’t seen anything similar at the other regional museums at Mesa Verde, Aztec Ruins, or Edge of the Cedars. Some of the features pointed out are the type of temper material added to the clay to prevent cracking. Studying these tiny grains provides clues to when and where the pottery piece was manufactured. The types of paint used can be distinguished under the microscopes also. The subtle differences between vegetal and mineral based black paints are among the examples.

Another exhibit where pottery pieces can be handled is an unnoticed drawer below one of the cases of whole pots. The display shows some of the regional styles represented as broken pieces as a hiker might find them. These different styles could be found anywhere due to trade.

One of the questions posed is was it the pottery that was traded or was it the contents of the pot.  Some time spent in the Anasazi Heritage Center might inspire the desire to examine these pieces in the field and leave them there for others to do the same.

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.
