Dottie Little Tent is correct. The Northeast Ridge Routes on Jackson do indeed make an ascending traverse on the right (north) side of the ridge up there where the ridge is narrow. That traverse is first across a steep gully, then on little scree covered chutes that angle upward, and finally by climbing back up to the ridge. If these areas are still snow covered most folks put the climb off for another day. Dottie Little Tent's photos should prove enlightening.
The 1/4 mile of avalanche debris below Gunsight Lake had a route through or around it flagged recently but it is still a pain getting through there. Also there is no bridge over the outlet stream from Gunsight Lake so a wade is required.
