I obviously am not very proficient at following up leads on a computer. I am still on dial up. While my wife, daughters, and granddaughters are on their speedy hi speed internet laptops and I Phones I get by with my less than 1 GB desktop. Ho!
Picked up a couple of leads from the posts. It is definitely a bushwhack up Lease Creek to the lake at the base of the North Faces of Carru and Osceola. Secondly, there is at least one party which has traversed the base of the North Faces of the two peaks and gone out by way of the col between Osceola and Carru.
It appears that no one so far has attempted a complete circuit using the north side of the three peaks and connecting up Ptrarmigin Ridge on the east side with the Pt Defiance Ridge on the west side of Lease Creek drainage and coming out at the Guard Station on the Pasayten River at the base of the Tatoosh Butte Trail, The only picture I have found of the Pt Defiance side of the route is in Becky's Guidebook. It is my understanding that both the Pt. Defiance Trail and the Pleasent Valley Trail which connects to the Fred's Lake Trail are either gone or in bad shape lacking any repairs over the last twenty years. Still looking for pictures taken from above Lease Lake of the Northeast Face of Osceola and the North Face of Carru. Also looking for pictures from Pt. Defiance Ridge back at Osceola and Carru.
Will keep looking!
