I don’t remember specifically, so take this with a grain of salt, but the trail is only minimally tree covered. Lots of burn damage. Some shade/ trees on the trail around Fish Creek and Fish Creek Saddle, but other areas exposed. e.g. the trail to the summit from Fish Creek Saddle is essentially completed exposed.
I’ve posted a couple of trail reports with pictures of my trips to Fish Creek Camp and Fish Creek Saddle recently.
