Observations and Notes

Arrow Quest 2018

We tried to get to this site on June 7, 2018. The road leading to it was very rough. At the point where we were to leave the road, the new track was very soft and sandy. We did not feel comfortable diving where me might get stuck. We did not get close enough to launch the drone and decided to leave this location for someone more adventurous to film. If you make it to this site we would love to feature your photos.

Greg Miyake and Sarah Kim write:

Reaching the Solomons Knob beacon was no easy task. We attempted the hike in September 2015 and after twenty or so minutes of a constant uphill battle upon crumbling, loose rocks in 100F desert heat, we reached the summit. The site itself appeared completely unaltered - no trash, graffiti, or signs of human presence. The only motion at the top came from a mouse that had claimed the old generator shed as it's home and two crows circling high overhead. We did not measure the arrow, but as you can see in the pictures it is intact and appears to be in good condition.
