It has been a very long time since I summited Tyndall, but if I recall correctly, there was nothing difficult about it. We went up the north side, directly accessible from Shepherd Pass.

At first, I thought comparing Mt Tyndall to Mt Dana is a pretty good estimate. But, when looking at both on the on-line maps, and converting the Tyndall map's meters to feet, it appears that the way up Tyndall is much more elevation change in the same distance. So from that standpoint, it might be more difficult. But... it was still NOT a difficult route.

The only thing I remember about it is losing my nalgene water bottle down the steep north east snow slope.

We spent a night at Shepherd Pass, climbed Tyndall in the morning, and then moved our packs down to Lake Helen of Troy (only a mile, but I recall it was rough). We then climbed Mt Williamson the same day -- it's short class 3 - 4 crack was memorable. We spent the night by Lake H of T, in the worst wind storm I have ever endured outdoors.

We had planned on then moving south over the 13000' ridge to Mt Barnard, Mt Russell, and Whitney, but after that wind storm and other issues, we bailed. We sure set some pretty ambitious goals way back then!
