I need to move about 15m of scoria down to the bottom of a steep section, about 20-25m. There's a steep, narrow, essentially unusable driveway that runs down there, but it's too steep, and with spilled scoria far too dangerous, to take a wheelbarrow down. At the moment the best option seems to be to use a skid-steer loader to truck it all down, since it can then also deposit it where it's needed. Another possible alternative is to set up some sort of chute, but the details get a bit vague... has anyone had to do this before and have any suggestions?
