Great Video ! love it !!
old reprint of long ago : concerns the recent interest in northern walking.
" In the steep mountains the are numerous gullies feeding the canyons in which one will walk. Each gully has it’s own little fan shaped debris field, and many of these look like perfect camp sites. Feel free to not use these as camps early in the season (May/June). Slush flows, which are tsunami like landslides of ice, gravel, mud, and large rocks, can flush over them in a heartbeat. The warning as such, which sounds like an airliner about to land on your tent, allows insufficient time to flee. Whenever one is camping near a gully outlet, or in downstream range of one, it may be wise to set up a bit high on the slope next to a large bush. The fantasy being that the bush has seen many seasons and has yet to be buried. Your basic slush flow has considerable velocity and can carry some way across the valley. One can view their remains at the outlet debris fields in many places. If one finds a winding path of hard packed snow/rocks in concert with perhaps a 5’ high wall of drying mud, you got yourself a flow. These are predominantly an early season thing. One can view up a gully and gauge the amount of debris still to descend. A prime event ready to occur will reveal snow covering some of the high ground, with a bloated slug of it laying in the groove and ideally this having a distinct blue’ish hue. Something like that will be gone by morning. Consider that it’s probably not the only one around and plan accordingly. "
David and Buck can explain it better, but the idea is .. be aware the one is actually outside, and that it doesn't much care.
in real life, we've had one of these beasts slobber right by the tents. it was awesome (terrifying is what it was). it was also very convenient that we'd recently had a tiff over whether to camp at the bottom of that very spot ... or not.
moral : it's better manners to keep your partner/client alive than to let them have their way.
