About 0.5 miles south and east of the odd rock cairn is the head of Bridge Canyon. This canyon runs north and south and is to the east of the Hackberry and Horseshoe Ruins sites of Hovenweep. I thought Bridge Canyon might be a similar location to the canyons that support the large Hovenweep sites. I hiked along the west rim of this canyon for about 0.5 miles and noticed two leafy green trees near the canyon head and some pools of water on the canyon floor.
Oddly, there is another large rock cairn about 1 mile south of the old corral, but not near the road bike trail. I haven't seen cairns this big anywhere else in the Canyons of the Ancients.
To the west of Bridge Canyon, north of Hackberry Canyon, are some hilltop areas with good views and extensive sagebrush fields. Despite these favorable features I didn’t see any ruins sites in this area. I did three separate hikes in this area, each was about 3:00 hours.
