Question about camping

[WayOutWest]

So Wildrose Camp would be sketchy in early March? It's showing as currently open, in early February....I wonder if snow and/or ice could be a problem there in the winter.

I've never seen snow there in March, though anything is possible.  Last year I was there the 3rd week of March and Wildrose looked pretty full each day (I was just up there hiking a few days, sleeping at SPW - indoors).  Chilly I am sure, so sort of depends on what kind of gear you have and what you're looking for.  When I'm out in March I carry a menu of possible hikes ranging from the valley floor to the higher Panamint peaks, and choose depending on the weather.  If you thought it was too cold you could drop down into the Panamint valley for the night and wild camp outside the park, but I don't have recommendations about spots.

I will be looking around Panamint Valley for possible spots, yes.  I haven't done enough exploring in that area....for instance have never been to Darwin or Darwin Falls, so would like to get there.  
I see in my notes that I've hiked Surprise Canyon in the past, but I don't recall that, must have been a long time ago, so I'd like to go there again...
