The trail takes its name from, you guessed it, the view of six glaciers from the top. It could just have easily been named for six trees or weasels or anything else because the view is so beautiful you pretty much forget to count how many glaciers you can actually see. The only thing I thought to count was the chipmunks sneaking around for crumbs while we ate lunch.
The view right there from the creek at what is officially the end of the trail is enough. But if you want to go further you can do an extra 1.3 kilometers up the valley to a better view of Abbot Pass and the glaciers. It is absolutely worth the effort.
And speaking of a considerable cooling, on our way back we had to take off our shoes and wade through the edge of the lake. On our way up in the morning the water level was lower and the stepping stones along that stretch of shoreline were exposed, but the day's meltwater raised the lake level a few inches in the few hours we were gone. Since we were plenty hot from our hike we thought it would be refreshing. And it was, in the same way that Simon Cowell is a bit critical. I have felt some cold water before, bone-chilling cold even, but this lake took the cake. I had to pee almost instantly (but I didn't).
