I remember one of my first summers in Grand Lake there was alot of talk about a festival up at Strawberry Lake. The trail head starts off the road to Monarch Lake and heads towards the Indian Peaks Wilderness Area and after a steep hike ends up in this meadow. The "festival" was not long after 'Woodstock' and rumor had it that there would be thousands of 'Hippies' invading Grand Lake, which had plenty of it's own in the late 60's and early 70's. It was really a gathering of the 'RainbowFamily of life' (whoever they are) and other than people taking showers at the car wash in Granby, I don't know if there was any kind of impact in Grand Lake despite all the talk and worries by the locals.
So anyway, it's a nice little hike and a beautiful view of Arapaho Peak awaits you. There are a couple remains of some old log cabins but not much else left by humans. No signs of tie dye's or meadows of hemp; just things the way nature intended it to be.
I'm not sure of what my point is here, except to say that, in time mother nature will handle things and eventually the pine beetles will be gone and new trees will grow where the dead ones stand now and life will continue to grow and flourish as always.
And I hope there will always be hippies!
