Look out to the east from Portland and your attention draws to the snows and glaciers of Mt. Hood.  But search a bit to the left and you can notice another bulky mountain with a notch on its northern rim.  This is Larch Mountain one of three shield volcanoes sitting in a line of volcanic vents making up the Boring Lava Field range stretching from Mount Sylvania on the southwest edge of Portland all the way east past Larch Mountain to Beacon Rock standing near Bonneville Dam, almost thirty miles apart in a straight line. 

Larch Mountain sits on the western end of the canyon of the Columbia River Gorge rising just over 4,000 feet above the river running about three straight miles to the north of its peak.  Coming from the east along the river, Larch Mountain is the last significant Cascade peak on the Oregon side of the Gorge before the mountains begin to ease topographically into the northern end of the Willamette Valley.
