They had no names in our language, and I did not know the native ones, so, remembering that at the foot of one I had found some ant-hills covered with beautiful diamond-like quartz crystals, I called it Diamond Butte, and the other, having a dark, weird, forbidding look, I named on the spur of the moment Solitaire Butte.

These names being used by the other members of the corps, they became fixtures and are now on all the maps.

I had no idea at that time of their becoming permanent.

This was also the case with a large butte on the east side of Marble Canyon, which I had occasion to sight to from the Kaibab.

It stood up so like a great altar, and, having in my mind the house-building Amerinds who had formerly occupied the country, and whom the Pai Utes called Shinumo, I called it Shinumo Altar, the name it now bears.
