Areas were mapped at a variety of scales, the most common of which being either One inch to 4 miles and One inch to 8 miles. Perhaps the most notorious sheet of this collection is the famed Yosemite 1888 sheet, which was mapped at a custom scale.

Many sheets came in three versions, the color reflecting land use, and tan and gold fill to emphasize physiological features, as in these two sheets also at 1:4

Snake River Basin

Great Salt Lake


This Grand Canyon sheet is at 1:8 and extends from 111-113 degrees longitude west

It also represents how there were collaborative mapping efforts underway during this era of North America’s transition into the United States
