Cochetopa Pass - eastern side of the map.
On this map, what is now called the Gunnison River is labeled
as the Grand River. The northern part of what is now called the
Colorado River (north of the mouth of the Green River) was called
the Grand River by some, and on some maps. This was changed in 1921,
when the State of Colorado petitioned to have this part of the river called
the Colorado River. On this map, the part of the Colorado River north of
the mouth of the Gunnison, is called the Blue River. In the text,
Beckwith writes that it's inaccurately called the Grand, when it should
be called the Blue River.
