This is a steady strenuous grade for 4 miles and 3300 feet up, and we'll be trying to keep a steady  brisk pace for exercise, so please register for this hike only if you are already in condition from recent hikes of this difficulty and pace.  Teen family members are welcome if they are in shape, have the right gear, and are able to keep up.

We'll go rain or shine, so pack your raingear and ten essentials as well as warm non-cotton layers to shed while we climb and put back on at the top.   Microspikes and at least one trekking pole are required for the icy section at the top.

More details will be provided by email as the date gets closer. The destination may have to change based on conditions.
