We hiked up the trail a bit. I believe this white rock is an erratic. It's always fun to see them; especially since they are not common. However, this area is at a meeting of the glaciers in the area.
A small, vigorous glacier coming down Mill D South Fork met the larger sluggish glacier from the main canyon and the two wedged together and stagnated at this point.
The boulders and pebbles from local and distant rocks that were carried by glaciers are of many different types, including limestone, sandstone, quartzite, granite, and basalt. Rocks that have been transported into an area from far away are called erratics. In geology an erratic is any material which is not native to the immediate locale but has been transported from elsewhere
