Erosive Landforms in the Microcosm


Location

The hashpoint is on a utility corridor (gas pipeline, petroleum pipeline, electrical powerlines, and possibly more all going the same way) on the side of a bluff just south of State Route 56 at Carmel Creek Road.

Participants

LucasBrown

Expedition

A car was employed to transport the hasher from his house in Poway to an apartment complex at the southern terminus of Carmel Creek Road in San Diego, near the juncture of Carmel Valley and Sorrento Valley. Upon reaching the complex, the hasher disembarked and proceeded up a steep, narrow trail up the bluffs. Upon reaching the top of the bluff, some time was taken to record the geological and biological features of the bluff, including some rather spectacular erosive landforms. The hasher then proceeded to the hashpoint, located on a slope inclined about 60° from the horizontal, recorded the location with screenshots of the Geohash Droid app on his smartphone, and left.

  • Exhibit A. This cleft is the northern side of the ridge containing the hashpoint.

  • Exhibit B. Hard sandstone atop the bluffs. The sediments underneath this hard layer are comparable to volcanic tuff in terms of erosibility and foreign body inclusions.

  • Exhibit C. A different perspective on the cleft in Exhibit A.

  • Exhibit D. Photograph taken from nearly the same location as Exhibit C but with a slight counterclockwise rotation. The slope containing the hashpoint is just out of sight between the two rises in the middle of the photpgraph on the left (southern) side of the ridge.

  • Exhibit E. Photograph taken from the same location as Exhibit D but with a slight counterclockwise rotation. The hashpoint is on the right (northern) side of the cleft.

  • Exhibit F. Erosive landforms on the slope containing the hashpoint.

  • Exhibit G. Erosive landforms: a cascade and plunge pool with depth about one meter.

  • Exhibit H. Erosive landforms. A tiny hoodoo about 5mm in height.

  • Exhibit I. Erosive landforms. Another tiny hoodoo, somewhat larger than Exhibit H.

  • Exhibit J. Erosive landforms. A small slot canyon about 0.5m deep.
