the floods began and came pouring down the arroyos, and at one 
place we crossed an arroyo with great difficulty. A little later while 
the others of the party were ahead, having safely crossed one of 
these danger places I heard the flood coming. I was leading. my 
horse at the time and rushed forward, managing to get through the 
first rush of water with a second or two to spare. The water was 
the color of chocolate, loaded with small stones and other debris. 
A moment too late would have meant being drowned or marooned 
until the mad flood subsided. I was told that several persons had 
lost their lives by arroyo floods in these mountains. July 28th. 
we left for Moab and Thompson and found the temperature 96° 
in the shade; and the train we intended to take for Salt Lake City 
was seven hours late. The canyons around the City of the Saints 
are entomologically rich, far more so than in the Sierra La Sal. 
At the former place about 115 species of butterflies have been re- 
corded. Returning we spent a few days at the higher points on 
the Union Pacific Railway, Evanston, and Laramie in Wyoming. 
We enjoyed our stay in the Sierra La Sal. The mountains are of 
interest to the geologist and mineralogist as well as the botanist 
and zoologist. The highest mountains are Mt. Peale (13,089 ft.), 
Mt. Waas (12,586), Mt. Tomasaki (12,271), and Tukuhnikikivatz 
(12,004 ft-) This last name is of Navajo origin. Carnotite, the 
ore of radium is mined, as well as gold and other metals and min- 
erals. 
In the summer of 1911, P. A. Rydberg collected botanical speci- 
mens in the Sierra La Sal and I know of no other naturalist who 
has visited them. 1
