Gorgeous mountain ranges in Oregon are choice locations for hunting morels. Be sure to check out forested elevations of the Cascade, Blue, and Klamath mountain ranges in the 4,000-to-5,000-foot levels, since these elevations host temperatures that are ideal for morels.
Hunt for morel mushrooms in Oregon starting in April even if the temps seem a bit chilly because they are first among mushrooms to erupt above the blanket of leaves. Oregon summers in 5,000-foot elevations can sink to temperatures in the 40s Fahrenheit and below, providing for a very long season of morel hunting into August.
Burned areas in Oregon's pine or hardwood forests are prime areas to start hunting for morels in April, states an article by Ian Gibson of the South Vancouver Island Mycological Society. Make note of forest fires that occur from September through November in Oregon, since morel populations are higher in areas where charcoal residues are found.
