I would be down to help with a clean-up. Aren't there refrigerators and stuff like that down there?
Yes, there's an old snowblower and a couple of bicycles for sure. Some of those larger objects would take a serious haul system setup to get them out. If only someone had the skills and know-how to setup a cable across the gorge for a hauling system....hey, wait a minute... :-)
I've been meaning to try to get a cleanup day organized for quite some time. I'll move this idea higher up on my list and publicize it if it materializes. I know a number of local canyoneers use the gorge quite a bit as well and would be interested in helping out at a cleanup day.
