makes a memorable and harrowing tale. In the words of Albert Ellingwood:
Despite the serious and daunting objective hazards, the first ascent team completed the climb and descent safely in a feat of mountaineering skill.
Appearance
The appearance of the peak is reported to have changed significantly due to a landslide in 1911. From the December 29 edition of the ''Mancos Times-Tribune'' of that year:
There are several photographs of the peak from before the landslide. Before-and-after photographs taken from the north and shown in ''The RGS Story'' indicate substantial change. The earlier photograph shows a taller squared-off peak that would be more suggestive of a lizard's head.
Before-and-after photos shown in Jackson and Fielder's ''Colorado 1870-2000'' taken from the south do not show as much change in appearance, indicating that the area of collapse was on the northern side.
