On my GPS map I found a trail that starts from Lightning Lake and goes up the ridge to meet the Skyline Trail.
I was wondering if anyone has done it and if it's still maintained: I cannot find any name for it..but you can see the Google Earth screenshots of the loop I was thinking.
I am not too worried about the ridge portion, but the start of it seems very dubious to me
I have done this trail as a loop from Strawberry Flats descending to the lake and then looping back to the car. The trail is well marked and well-used from what I remember. Not sure of current trail conditions...
Here is a link to the park map which shows the trail:
