This is what a well-placed cam should look like in sandstone.

did ya happen to click for the enlarged version? looks sketch to me.(contact area wise) and just think it's the piece above the nut I just fell on.

looks better than some of the great Fisher Towers cam placements. It's even creepier out there when your cam starts grind it's way out! I also learned a fun lesson about placing TCUs in soft rock out there: they'll hold for a few minutes and then shear out unexpectedly.

The right-sized alien with it's narrower head, as well as more flexible single-stem, would probably fit in that hole much better.
