in a southeasterly direction through a narrow steep-walled canyon for "bout 22 miles to jOln:1on',l,,,.entCreek in wes"o Colorado Springs . The watershec is typical mountain te.rain with steep .ough slopes. Ele- vations range from 14.110 feet at Pik~5 Peak through 5,948 feet at the mouth of *,numel'.t cr""k. A per"l'_nial stream. fountain Creek's headwaters are fed from glacial sno~~acks ar~ springs in the alpine northern sloped canyons of pikes Feak and from glacial deposit" "ohat persist in many valleys above 9,500 feet elevation.
