NOTES ON SOME PLANTS OF THE ARAPAHOE 
NATIONAL FOREST AND ROCKY 
MOUNTAIN NATIONAL PARK 
L H. PAMMEIv AND R. 1. CRATTY 
One of us accepted an invitation to spend ten days in August, 
1919, with the forestry students and Professor G. B. MacDonald, 
Professor G. C. Morbeck and Mr. D. C. Poshusta in the Arapa- 
hoe national forest. The camp was located at the junction of 
Spruce creek and the fork of St. Louis creek, near the ranger 
station, at an altitude of about 9,000 feet. 
Mount Byers, one of the outstanding peaks of the region, was 
easily accessible. We are under obligations to the forestry de- 
partment for the many kind courtesies shown us. 
One of the most interesting botanical regions of northern Col- 
orado is the Arapahoe district. The Arapahoe district in the 
present paper comprises the Arapahoe national forest and the 
Rocky Mountain national park. It is rich in scenic beauty, and 
of great interest to the scientist. The Rocky Mountain national 
park of 358 square miles, was established by taking an area from 
the Arapahoe national forest and the Colorado national forest. 
The Geologic Story of the Rocky Mountain National Park, a 
pamphlet of ninety pages by Dr. Willis T. Lee, published by the 
Government Printing Office in 1917, is very profusely illustrated 
with maps and views of the scenery and gives a most interesting 
description of the region, and is well worth a careful study by 
any one interested in this section of our country. The Colorado 
national forest contains the headwaters of such streams as the 
North Platte, Laramie, Cache La Poudre, Big Thompson and 
Boulder creeks. To the south are the Arapahoes,^ a magnificent 
series of peaks. 
The Arapahoe glacier is on the east slope of the Arapahoe 
peaks. The glacier is three-quarters of a mile long and of about 
1 Dr. C. C. Parry, in one of his articles on The Far West in the Chicago Evening 
Jou7"nal, December 3, 1863, deplores the fact that the unmeaning term of Colorado 
(red) was applied to the then territory of Colorado. The name Arapahoe he thought 
might better have been used, or the worthier historical name of Jefferson or New 
Switzerland. It does seem to us as though this state with its magnificent streams 
and superb mountains should have commemorated the Indian.
