A spiral design can be seen throughout the work. The spiral design was used by the artist with a view of presenting perseverance. The artist seems to have found a number of examples regarding the spiral design as petroglyphs, which is common to many tribes. Each tree surface is covered using images as well as text, which chronicle the Indians history. Regarding the themes of each tree, they seem to be presented roughly in a chronological order. Tree One is the starting point of the artwork and it depicts imagery mainly from Ancestral Puebloans (Denver Art Museum). This comes out as a way of representing ancient times. Tree Two, on the other hand, shows the history of Bent’s Fort. It further explores the themes of coexistence. This exploration is specifically the relationships that are based on trade between the various nations presented. Bent’s Fort has a tepee and shows the existence of a close relationship between the tribes and Fort. On this tree, question marks are indicated in reverse form. These marks indicate the impression of the non-existence of peaceful trade relationships (Denver Art Museum). Tree Three deals with the tribes of Cheyenne and Arapaho. These two tribes occupied the eastern side of Colorado. Besides, two historic massacres that point to the destructive effect of the United States Amy as well as the expansion of railroad on the native people. The tracks, in this case, are read in terms of the railway’s wounds approaching the native communities.
