Sept* 3rd : liar died 25 miles up the Rio Grande; camped . 
at a ranch several miles above wagon wheel gap. In the open 
valley above the gap a patch of modern formation appears; did 
not examine it. A ridge of limestone outcrops along the river 
and near the bridge a massive bed is seen to lap up against the 
valley wall. Found small outcrops of porous, impure limestone 
at all points up to camp (see map). The drift in the valley is

timber line we encountered a heavy snow and rain storm; made a 
fire and waited for a clearing. Reached the summit at 11 o f clock 
and sheltered behind a small monument and ate lunch and skivered 
while a severe snow storm was raging. By one o’clock the clouds 
broke again and the mountains began to peep out. The famous

summits. One of those summits is very properly named Aeolus. 
Peak after peak came out and presently such an array of needle 
and spire like points were in view as I had never seen before 
and as cannot be found anywhere within the boundaries of the IMS,
