Start on the far right undercling, and work left making your way to the left sidepul through a series of larger moves, then head up the the traditional finish of “

Aerogel

.”

Aerogel Variant: MN

The Hard Traverse

Aerogel

Right after a huge, long boulder along the left trail at the base of the Second Flatiron is the Stardust Boulder.  Just to the right of the trail is the boulder.  Aerogel starts low and traverses left to a sloping rail.  Pull straight up to a crimp then the top.  Unlike some other problems around Boulder, the landing on this one is great.

Start the same as for

Aerogel

, except you continue right from the sloping rail around the corner then on to a neighboring block where you finish. This is not a bad problem. It is worth doing it you're already at the Stardust Boulder, but it is not as fun as

Aerogel

.
