There is going to be ice this year. It's looking to be a wet winter. The San Jacinto river is flowing well (time for some whitewater fun, yeah?).
Just to give some perspective, looking at some notes of mine;
First week of April, 2001, I did the Trough as an ice climb with Ruben Minjarez.
May 4th, 2003, ice-climbed the Trough with x15x15 and ONE WEEK LATER we did it again!
I think our May climbs might be the latest season ascents ever up there, but March almost always has climbable ice in the Trough.
But it's the North Face that's the ticket, as x15x15 notes. That's a trickier place. Deb has been there and can confirm. The ice is not as consistently melted and forms lots of ballbearing snow that promises but does not deliver.
But on occasion.......
As x15x15 said, it's spooky fun.
