I noticed this line when Emily and I were in the Lakes Basin and had to check it out.
6 Mile trip report here
I only made it 900′ up on my first attempt before getting blocked by an ice choke. I came prepared this go round and it paid off.
Above that ice crack was another icy choke, then 1500′ of tight chute goodness.
The line is about 2400′ top to runout. Another Bonneville classic.
