I am considering a trip to Death Valley in late March, never having been there. What temperatures am I likely to encounter? As I searched the sites on the internet I noticed mention of the northern sections of D.V. being the less visited and I assume least photographed. Am I accurate in that appraisal? It appears that lodging in that section of the valley is non existant...is camping the logical approach? Thanks for any information and guidance that you can share.
