GeoSights—Notch Peak—Big Cliff, Millard County, Utah
The enormity and vastness of the cliff forming the north face of Notch Peak is difficult to describe. Standing near the cliff’s base and looking up is awe inspiring. The view while standing at the top and looking over the edge? I would not know as I was on my hands and knees, too fearful to stand and look over the edge at one of the greatest vertical drops in the contiguous U.S.
Reported estimates of the cliff’s actual height vary significantly from under 2,000 feet to over 4,500 feet, which is likely due to differences in defining where the base of the cliff starts. Photogrammetry (measurements from digital stereoscopic photographs), verified with a paper 7.5′ topographic map, suggests the cliff has an uninterrupted near-vertical drop of over 1,500feet. The addition of cliff below a small bench 50 to 100 yards wide increases the distance to approximately 2,250 feet. Adding a portion of the very steep base of the sheer drop increases the distance to nearly 2,900 feet.
