This is not much of a trip report. I just thought some pictures and a quick description of this route might be helpful in case someone else is thinking about attempting Gladstone from the Slate Creek drainage.
I read a report about the Box Car Couloir and thought it would be fun to climb Gladstone from the same approach. I couldn't find any information on this route, but from Google Earth and topo maps, it looked possible to gain the Southeast Ridge on snow.
I was right. There is an obvious couloir that leads to the ridge...it starts around 12,800'. As I was heading up, I started to realize that the ridge was going to be tougher than I expected. I saw the tower that stopped me as I was climbing up the coiloir...had a bad feeling about that thing. I just didn't feel comfortable climbing it in ski boots and without a rope for the return trip. The snow that is in the left of the tower picture is not an option...it looks like it might be in the pic.

That's one bad ass tree

Looking back down the ridge at my skis and the ridge to Cross Mtn
The first few turns were a little intimidating
Slate Creek...don't be tempted to follow the creek all the way down...not fun
