I plan to review accounts of the Lewis and Clark expedition in western North America.
Living "off the land" made food security very vulnerable on journeys of several months.
You ought to be able to carry food and drink for 48 hrs.
Your Boone adventure challenge reads like real fun.
Even shelter. Looking out my window expecting another 15-30 cm snow tonight,
exploration comes to a stand still in 200-300 cm snow. Shelter is the issue.
Should have started work on that back last June.
Pit house or log cabin and a secure source of heat. -40C is brutal.
There's a demonstration pit house at the University of Norther British Columbia.
Probably 10M in diameter, 6' into the ground and 2' of earth spoil on the log roof.
Took a summer for a crew of a dozen to do by hand.
With a couple of cords of fire wood, I'd like to experience winter living for a few weeks.
Better yet with say 3 others for the social context.
