Analysis

The pilot made two enroute stops at places other than planned because he was confused and disoriented. When he could notget a sectional chart he wanted he tookoff without it after one of these landings. After the second landing he took off ignoring a red light from the tower. He listened to a weather report on the acft radio and even though the weather was deteriorating he continued on trying to maintain VFR. Unaware of the high terrain between Colorado springs and denver and seeing lights to the right and left the pilot thought he was in a valley and flew into a ridge suddenly with no warning. Local residents said there was strong winds, blowing snow, and low visibility at the time and place of the accident.
