Horseshoe to Whitney Portal over Crabtree would be NoBo, i.e coming down the traced route, rather than going up, a tricky traverse and slog up the beach to Discovery Pinnacle. The route pictured is looking SoBo, could be part of Portal to Horseshoe.
Precipice Lake is far from here, on the Western third of the High Sierra Trail. You could pick up that trail west of here, at Crabtree Meadow, and take it 40 miles west over Kaweah Gap, but no, its not near here.
