Greetings from Southern Oregon,
West of Crater Lake in northern Jackson County, there are stands of maple that turn orange and crimson this time of year. East of Crater Lake, the fall color show is put on by native aspens. The main concentration is in the Fort Klamath area. But there are numerous groves in the vast Fremont National Forest scattered in the upper reaches of the Sycan, Chewaucan, Sprague and Williamson rivers, between Klamath Falls and Lakeview, according to the Oregonian.
Here’s a story from the Mail Tribune newspaper about some of the best aspen viewing: http://www.mailtribune.com/apps/pbcs.dll/article?AID=/20071011/LIFE/710110301&cid=sitesearch
