About 80ft high, I'd guess, it is beautiful rather than vast - a rushing stream that catches the light from an opening in the forest canopy and plunges into a pool where there were two people bathing, and from which, surprisingly, they produced a large basket of freshwater crabs.
Every tricky traverse in mountain, stream or forest needed doing twice over: once to find a way for himself, then to collect the steed, often carrying it shoulder-high through sharp palmetto, or water, or rocks.
