Denver resident David Lesh posted photos on social media that he says show him snowmobiling at Keystone Resort in April. The photos could play a major role in his trial, set for July. A federal judge has denied David Lesh’s last-ditch attempt to get two criminal charges dismissed for alleged illegal activity on national forest lands before the issue heads to trial. The ruling earlier this month by U.S. Magistrate Judge Gordon Gallagher sets the stage for a July 22 and 23 trial on petty offenses, charging that Lesh operated a snowmobile on a closed section of Keystone ski area and that he sold or offered to sell merchandise without authorization while at Keystone.
