Lewis and Clark carried an iron framed collapsible boat with them on their 
journey across America in 1805. They had to abandon it at the Upper Portage 
of the Great Falls of the Missouri River in Montana "because they lacked 
materials - pine pitch and needles for sewing hides together - necessary 
for making the vessel watertight".

We don't have such an option....
