Hanging Lake is Correct!
All i remember is the Eisenhower Tunnel and then our next stop being Hanging Lake trailhead. When you're only going 55 and everyone else is whizzing by... distance is kind of irrelevant, LOL.
One of my favorite places to hike ... and my fav picture of the trek:
And just before you take the final climb to the lake you can veer left and see Spouting Rock..
You're Up Badnick!
