Perhaps The Finest Early Map of the Yosemite Valley
The map extends west to Coulterville, Mariposa and Bear Valley, north to Hetch Hetchy Valley and Hetch Hetchy Falls, northeast to Mono Lake, east to the Minarets and an unnamed Mammoth Lakes.
The detail in the valley is impressive, with roads and three Hotels already depicted.
As noted by Rumsey:
This map is among the most detailed and largest scale maps of Yosemite issued during this part of the 19th century, rivaled only by the Wheeler Survey map of Yosemite published in 1883. . . This is the same as the first issue that appeared with the Yosemite Guide Book . . . except that it adds "Hite's Cove" on the Merced River just slightly west of its junction with Devil's Gulch. In the (1870) third issue . . . Hite's Cove is relocated to a point just south of the Merced on the road titled "Road to Hite's Cove" and the erasure of the prior label is apparent. We have dated this second issue (1869) as a best guess.
