103 F in Death Valley at Furnace Creek on 31 March 2011 broke the record for the month of March. However, this did not establish a new state record for March which still belongs to Ogilby CA with 105 F recorded 111 years ago in 1900. Ogilby lies about 10 miles NW of Yuma AZ and appears to be a near ghost town at the intersection of Side Winder Rd and American Girl Mine Rd. Here is the record report from NWS Las Vegas:
