As Paul Schurke and I worked our way down the upper Rio Roosevelt we started encountering more and more of the major rapids that the 1914 Roosevelt Rondon Scientific Expedition spent days portaging around.
We had relatively light packs, and a 65 pound canoe, but it was still hard work in the equatorial sun. We were able to line the upper portion of this rapid, but the lower rapid was really big. We camped on a rock out crop just above the major rapids so we would be ready to complete to portage in the morning before the sun rose too high in the sky.
