Until this page is complete, I suggest this video of my summer climb in 2012; it includes a map of the route and useful information. Expect anywhere from a 3.5 - 7 hour ascent depending on your fitness level. Do not think you will get down quickly, the same lava rocks you struggled over on the way up are just as difficult on the way down.
This picture shows the differences between the summer (in red) and winter (blue) routes. As you can see, the winter route is longer and includes additional elevation, but you don't have to do the rock-hopping in the winter so getting down is much faster.
The summer route starts at Climbers Bivouac and the winter route starts at the Marble Mountain Sno-Park, but they both converge at Monitor Ridge and end up at the same summit point.
