10 Mile Rock is a highly recognizable feature when floating the Colorado River through the Grand Canyon. The pointed end of the large slab near the nadir of the panorama points downstream towards where 10 Mile Rock lies resting in the shadows in the river below. 10 Mile Rock gets its name, obviously enough, from the fact that it is about 10 miles from the beginning of the float trip which starts at Lee’s Ferry. It is almost always passed on the first day of rafting. 10 Mile Rock is an enormous slab of rock that has fallen from the cliffs above and landed on its edge so that it extends well above the water line.
Many float trips that launch late in the morning, or even after lunch, end up making their first camp at Soap Creek just after passing 10 Mile Rock. Soap Creek’s confluence with the Colorado is easily seen in this panorama as the viewer looks down river. Soap Creek created the large canyon, on river right, that joins the Grand Canyon a couple of miles below this view point.
