You might try calling the park for an info. check.
I will likely be out hiking peaks, canyons, and dunes in DV again very soon. I may be able to provide some details if I camp at Mahogany Flat again and do some hiking in that area. Also, I was there 4-5 weeks ago and hiked Telescope Peak. Hopefully someone with more recent specifics will chime in here or on Death-Valley.net. In the meantime, I can report what I observed when there and while researching for the coming trip.
On my hike, I was fine in hiking boots with trekking poles. Snow/ice was patchy and only a couple of inches deep down near the trailhead, mostly limited to shade and north/NE facing slopes. It was sometimes slick, but mostly avoidable. After rounding along Rogers to more E/SE facing slopes, it was completely dry/snow free until nearing the flats between Rogers and Bennet. Snow up in the meadow ranged from a few inches of soft, well-packed tracks to a couple of feet of soft snow in north facing spots off-trail. Some of the rocky, flat areas near the trail were dry. Deeper (1-2 feet of soft snow) became unavoidable on the steep switchback/ridge climb to the northern point of the Telescope Peak summit area. Sometimes it was easier/safer to find and hike up the ridge than to find/attempt portions of the final steep switchback section. Up on the very top, the snow was shallow/dry spots to sit were available. Ice was not really an issue aside from the slick patches near the beginning of the hike that simply required awareness. My main concern would be that conditions might now be more slick up on the steep switchback/ridge climb to the summit.
The Panamints got a bit of rain/snow within the past couple of days and probably also did in some of the other late Feb.-March storms. It may not mean much about conditions up higher, but I noticed that reports of snow at the Charcoal Kilns on the DV Morning Report http://www.nps.gov/deva/upload/Morning-Report.pdf
ceased sometime after I returned from my last trip.
Your probably saw the Sierra Nevada Gas Prices
thread that had DV information. Being that I can't buy diesel there, I had forgotten that prices in Stovepipe Wells are likely cheaper than in Furnace Creek, (but still much more than in NV). Depending on the specific vehicle and specific plans, getting fuel at Stovepipe Wells could make a lot of sense.
Here is a website that tends to have a bit more information than others I have seen (but still no Stovepipe Wells) and also a smartphone app: http://www.gasbuddy.com
