This is pretty nuts: even going fairly hungry, he will start with at least 150 lbs of food, so he&#x27;s probably starting with 200-225 lbs of stuff, climbing from near sea level to the 10,000-ft Antarctic plateau.<p>It&#x27;s also pretty dumb:<p>&gt; Henry will make the first solo descent of the Shackleton Glacier.<p>While going unroped on a glacier can be far safer than is often preached, it&#x27;s not something to brag about.  Falling into a crevasse is much less predictable than falling off a cliff, so this guy &quot;free soloing&quot; a hairy glacier is much more like Russian Roulette than e.g. Alex Honnold free soloing Half Dome.
