Heads up if you were interested in summiting Mt. Perry in Death Valley Nat'l Park:
https://www.nps.gov/deva/learn/news/dantes-view-closed-for-upgrades.htm
"Death Valley National Park will soon be improving parking and viewing platforms at Dantes View. Due to the construction project, the scenic viewpoint will be closed temporarily to public access from January 23rd to early April 2018. "
Mount Perry is ususally climbed by driving up to the viewpoint, then hiking over to the summit and back. But apparently that won't be possible for a few months.
Judging by the discussion on DVNP's facebook page, the gate on the paved road up to the viewpoint will be locked. This gate is located just above the trailer parking area and the juncion with the unpaved Greenwater Valley Road.
