Picture Canyon (Colorado)

It is a small canyon with easy slopes, springs, picnic tables, and a loop hiking trail 4 miles (6.4 km) long.

Material goods found include corner-notched projectile points used for bow and arrow hunting and cord-marked Woodland grit-tempered pottery.

[2] Their homes, built on the lowest portion of a mesa or above the creek flood plains, provided great visibility in three directions and easy access to the farmland.

They were covered by wooden poles, brush and possibly animal hides and contained hearths up to 19 feet (5.8 m) wide for cooking and warmth.

Material goods included metates and manos for processing acorn and maize, and tools made of imported chert, obsidian and petrified wood.

[1] Horizontal lines of writing were found there, similar to 50 sites in Oklahoma and southeastern Colorado, which have been translated to include solar, planting and travel related information.

Picture Canyon is typical of the canyons in the Comanche National Grassland .
