Douglas Mawson, Aurora Australis (1909)
“ This lower zone through which we now passed, was not altogether composed of dead material, but supported abundance of saprophytic types, chiefly fungi and bacteria. No human being could exist long under these trying conditions, so that it was with joy that, after two days, streaks of daylight began to penetrate the tangled mass above. In a comparatively short time, clear sky stood above us, and the walls of rank vegetation on either bank slowly dwindle as we proceeded. With the return of daylight our spirits rose. ”
