This is a longshot. I've been wondering for years where I was when I saw this canyon. I was about 12 years old. My family was out driving around the West. We might have been headed for Baker Oregon (from California) as we had relates there. Anyway, it was hot, we were in the middle of nowhere, nothing but dirt and sagebrush and a two-lane road. We stopped and there in this nowhere was a canyon, not very wide, but really deep. A little creek had cut the lava flow. I threw a couple of rocks in and off we went. I've asked my dad where this was and he thinks it was out by Bend. I've been to Bend and haven't seen it. Does this make sense to any Oregonians out there? Thanks.
