Passed overhead from approx. NE to SW. Seemed about mountain height. Observed for about 1 minuteObject was round, but irregular shape with dullish orange-red glow, texture of a sponge. No noise. Seemed to pass over low mountain in the immediate area. (Trail B.C. is located on the Columbia River, 18 miles north of the Canada-US border...150 miles due north of Spokane, Washington...about 400 miles due east of Vancouver, B.C.). Object seen by my wife, Dawn Glover
