Name for a piece of climbing equipment produced by
Black Diamond.
The alien is a very small camming device(
SLCD).
Most camming devices require you to find a
finger sized crack in the rock. The smallest aliens
(there are about four sizes of them I think) can fit
into fingertip sized cracks and in paticular
they can fit into holes left in the rock
when old pitons are removed (these are called
piton scars).
Aliens cost about $70 a piece. I have used them within
the last 6 months and they are brilliant. Black Diamond makes fantastic equipment and placing any piece of gear made by them gives you a little extra confidence on your climb
