Mr. Gannett that day, and intended, after talcing a glance around 
to determine on tomorrow's work, to descend to a little park 
that nestled at the west base and camp for the night. While 
looking about with my glass I noticed that a topographical monu- 
ment had been built on the summit of Mount Sheridan, which lay about 
a mile to the east, and on looking a second time was both surpris- 
ed and delighted to discover two men darkly outlined against the 
sky. A little later I joined my friends, and hastening down 
the precipitous northern face encamped with them at the head of 
Heart Lake.
