Vent: Got caught in a surprise hailstorm above treeline on the John Muir Trail last August
I had to wedge myself under a rocky overhang for 45 minutes near Muir Pass while golf-ball sized ice pounded my pack, and my rain fly shredded on day 3 of a 10 day trip - has anyone else used a tyvek groundsheet as an emergency tarp because mine barely worked.

Dude that sounds absolutely brutal. Muir Pass is no joke even in perfect weather, getting pelted by golf ball ice up there is a nightmare. Tyvek as an emergency tarp is basically just a trash bag with delusions of grandeur lol. It barely keeps rain off a picnic table, let alone a hailstorm at 12k feet. Honestly you probably got hypothermia risk just from the wind cutting through it. Hope your gear survived better than your rain fly did.

Fold that tyvek tight and use it as a windbreak on the leeward side next time, that's what I do. The real trick is combining it with your pack liner as a ground sheet for insulation from the wet rock.
