44 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 59 
Most of the field season of 1911 was spent in a continuation of 
the work of 1910 upon the fossil bed between Mount Field and Wapta 
Peak. Camp was established and a trail built to the fossil quarry in 
the shale 800 feet above. The secretary, with his assistants, con- 
tinued collecting as in 1910. This was a more or less tedious task, 
the monotony of which was relieved by the occasional discovery of a 
prize specimen, the exploding of a charge of dynamite, the passing of 
a party of tourists on the trail seven 
hundred feet below, or by sudden 
showers and snow flurries. In 
September a start was made for the 
Amiskwi Pass region northwest of 
Field. Rain, followed by snow, 
met the party on the pass. On 
September 22, the snow was so deep 
that the wild animals had left the 
higher canyons and ridges, and the 
party reluctantly retreated to Field, 
to meet there a snow storm that 
closed all field work for the season 
Of 1911; 
Mr. L. D. Burling spent the sum- 
mer of 1910 in the collection of fos- 
sils and in the study of the stratig- 
raphy of a portion of the rocks in 
the Yellowstone National Park and 
in the Big Horn and Wind River 
Mountains of Wyoming. The sec- 
tions measured were found to be 
essentially identical with each other 
Fic. ie Gea sce much similar to those of Colo- 
fossils at Glenogle, B. C. rado. The chief purpose of the 
work was the correlation and 
proper interpretation of the lower Ordovician fossil fish horizons. 
A short visit was made to the type localities in the vicinity of Manitou 
and Canon City, Colorado, and several hundred pounds of fossils 
were added to the collections. The latter part of August and the early 
part of September 1911 were spent in the study of the Lower Paleozoic 
rocks of the Van Horne Range and at places along the line of the 
Canadian Pacific Railway west of Field, principally at Glenogle.
