Our Leatherneck Ridge short-cut.
The complete Leatherneck Ridge route apparently begins at an elevation of less than 1000 feet on highway 111 and tops out at ~8700 feet between Cornell Peak and the upper tram station. We, however, started just below the lower tram station at an elevation of ~2400 feet. With all of the ups and downs on the final north ridge stretch, the total elevation gain of our variation is approximately 7000 feet. Though there is no sustained rock scrambling, there is enough of it, including lots of awkward traversing, to merit a class 3 rating.
At 6:15AM on February 13, Patrick Moran, Dave Gillanders, and I walked across the parking lot and immediately encountered our first obstacle: a creek crossing. The east side of the creek is covered in a dense, bouncy carpet of grapevine that is riddled with trip-wires. After negotiating this unusual terrain, we were faced with an awkward crossing that resulted in one drenched shoe. Unfortunately, that shoe was on my foot.
Across the creek, we immediately began climbing steeply up the obvious ridge, with occasional bits of scrambling here and there. After 2700 vertical feet of climbing, we gained Leatherneck Ridge proper, which afforded a striking view of Mt. San Gorgonio. I found the terrain on this stretch to be really aesthetic, with varied vegetation, flat sandy patches, and interesting rock crags reminiscent of Joshua Tree.

Eventually the ridge became steeper and brushier, leading to a gorgeous stand of tall conifers. These conifers were followed to the point where all of the subsidiary ridges, including Leatherneck Ridge, converge into a single, north ridge. At this point, we were suddenly rewarded with a breathtaking vista of the Falls Creek drainage, including the spectacular northeast face of Miller Peak.

The final stretch along the north ridge involves several peaks and notches and lots of tedious side-hilling. The last half of it was plastered in snow that was either icy or unconsolidated, which slowed progress. Further slowing progress was a bout of stomach flu that hit Dave with a vengeance. Consequently, that final 1.5 mile stretch took over six hours.

By the time we reached the crest, it was dark. Although the half moon directly overhead provided just enough light to illuminate our way, we donned headlamps anyway. Not wanting to take any chances, I consulted map and compass and closely monitored our bearing until the light of the tram station came into view. We entered the upper tram station at 6:45PM, 12.5 hours after starting.
