10,000 feet elevation the trail up the creek crosses over the upper mo- 
raine on the south side, and the view shown (Fig.2) is from this point. 
There are here inner and outer moraines, the latter 125-150 feet the 
higher. The inner moraine extends the farther out on the fan, differ- 
ing in this respect from the Zapata moraines. The height of the 
moraine from its foot on the fan to the top of the outer ridge is approxi- 
mately 500 feet. | Landslides in the moraine show its constitution to 
be true glacial débris. 
The various streams descending the south slope of Sierra Blanca 
likewise held their appropriate glaciers. The moraine in Little Bear

covered with a growth of pines. 
Creek reaches barely to the mouth of the canyon at the apex of the fan. 
Blanca Creek has a pronounced moraine, extending beyond the mouth 
of the canyon and down the slope of the fan, the older, outer moraine 
reaching the farther, and the inner one being the higher. The two 
branches of Ute Creek both exhibit moraines and glaciated contours, 
and contain several lakes in their upper courses. ‘The various streams 
which head in the Blanca massif number in their valleys some thirty 
lakelets, large and small. 
The valley of the Huerfano, heading on the northeast side of 
Blanca Peak, is distinguished from the others by the presence of 
living glaciers—small, it is true, but characteristic. The valley of 
the Huerfano, up to the base of the steep north side of Blanca peak,
