DRAINAGE DIVIDE

[Mile-marker 8]

About half a mile north of the farm road we reach the highest point on

Broadway (Colo. 340) at a drainage divide. Inasmuch as the three

Redlands Lift Canals end east of the divide, there is quite a contrast

between the lush irrigated lands east of the divide and the nearly

barren desert to the west, a view of which is shown in figure 43. To the

southwest of the divide is an excellent view of the

northeastward-dipping beds on the Lizard Canyon monocline. On the left

about a mile northwest of the divide we pass the other entrance of

Monument Canyon, then Lizard Canyon, and a switchback on Rim Rock Drive

ascending the ridge between Lizard and Fruita Canyons. The water well

beneath elevated tank on left is 650 feet deep and formerly flowed at

about half a gallon a minute from the Wingate Sandstone. Household needs

are obtained by pumping.
