Tripyramid South Slides Snowshoe: 1/6/25

On a cold but sunny day I returned to Waterville Valley for more snowshoeing to slides on the flank of Mount Tripyramid - this time on the SW side of the mountain. The Waterville Valley Nordic Center had groomed the first 2.2 miles of Livermore Trail - quite an accomplishment considering the thin cover. It made for a fast and easy approach.

 

Thanks to a spell of cold weather, the upper part of White Cascade on Slide Brook had largely iced over. Three days earlier it was pretty much free-flowing.

The mellow approach to the South Slide is one of my favorite trail sections.

The crossing of Avalanche Brook required some careful foot placement.

Into the Wilderness.

The gateway glade. I was pleased to find a snowshoe track, albeit a choppy one, on the trail. No boot holes!

 

Probing with poles revealed the thickest ice at this tributary crossing.

A small cascade on Slide Brook.

I didn't like the look of the trail crossing over Cold Brook.

Found a better spot upstream.

The snow off-trail in the hardwoods was firm and ideal for bushwhacking.

I enjoyed some meandering parallel to the trail.

These yellow birches have seen many hard winters.

Bushwhacking up through one of my favorite hardwood glades, unusually high at 2900 ft.

I returned to the trail briefly, then went off-trail again where it turns up to ascend the First (1869) South Slide. From here I headed south across the slope to visit the Second (1885) and Third (2011) South Slides. First I wandered across the lowest remaining open patch of the largely revegetated 1885 slide.

Then I cut back to the lower end of the 2011 slide, which was triggered by Tropical Storm Irene.

I climbed partway up it, but the cover was too thin and bony on the steeper part for snowshoeing.

I climbed up the bank at the edge of the slide for a good overlook.

Side view.

A view out to Mt. Tecumseh.

From there I whacked up and across the slope to two open patches on the 1885 slide. The snowshoeing was excellent on a deep firm base with a few inches of powder on top.

A nice vista from the top of this swath.

Respectable snow depth here.

Back into the woods to climb to the next open area.

An inviting corridor.

Pristine snowshoeing.

The best view is up there.

Due to a late morning start, I didn't get up here til mid-afternoon. It was cold, but with no wind I was able to have a half-hour second lunch break while admiring the view of Sandwich Dome and the remote Lost Pass region.

Some nice colors on the way back down the lower slide patch. At the base of this patch are two of the largest white pines I've seen on a slide at an elevation above 3000 ft. I made it down to Livermore Trail at dusk and snowshoed the last hour by the light of a half-moon hovering high overhead.

 

Avalanche Ravine: 1/3/25

Three weeks removed from my last all-day hike, I opted for a longtime favorite winter trek, out to Avalanche Ravine on the NW side of North Tripyramid. Out there I hoped to find some good off-trail snowshoeing in the Sandwich Range Wilderness backcountry. 

It turned out to be a fine early winter day, as seen in this view of an open field a mile up the Livermore Trail.

White Cascade on Slide Brook was still rockin' several days after the end-of-December rain.

The cover was thin for the first 2.6 miles on Livermore Trail, making for easy 'spiking.

As snow depth started increasing above 2000 ft., I followed the lead of one of the three hikers somewhere ahead of me and put my snowshoes on. It made for easier going even in just a few inches of crunchy snow.

All quiet in the Waterville Valley woods.

The junction with the north end of Mount Tripyramid Trail, 3.6 miles from the Livermore trailhead, was the launching point for my snowshoe bushwhack.

All three of the hikers ahead of me had turned off onto the trail leading up to the steep and imposing North Slide, though the solo hiker with a dog who I had chatted with briefly at the trailhead said she was going up Scaur Ridge Trail (after already climbing Tecumseh early in the morning!).

My route followed an old overgrown logging road on the north side of Avalanche Brook.

This old road leads to one of my favorite hardwood glades. The wind was roaring overhead, but it was not an issue in the protection of the trees.

The snowshoeing was not disappointing.

The road goes ever on...

Though snow cover was sparse at lower elevations, there was plenty above 2500 ft.

The inner sanctum of Avalanche Ravine.

One of my favorite old maple trees.

Sure seemed like winter out here.

A glimpse up to the top of the North Slide.

The lower part of the East Fork of the North Slide, with a frozen stream winding through.

I climbed a little way up along the East Fork. No sun here!

Then I headed eastward, up and across the south side of the ravine, aiming for an open strip on an old landslide. Along the way I had a glimpse of sunlit Scaur Ridge behind a gnarled old yellow birch.

Making tracks.

Sidehilling.

Arriving at one of the small remaining open strips on this old slide.

This was a fairly sizeable slide after it fell in 1885, about 750 ft. long with a vertical drop of 420 ft. and a slope angle of 29 degrees. It was one of several adjacent slides triggered by the August 1885 storm that unleashed the huge North Slide and its East Fork. The multitude of slides caused by that storm gave this nook its name: Ravine of Avalanches, or Avalanche Ravine. Alford A. Butler visited this ravine shortly after the slides fell, and described this one as "a broad, shallow triangular landslip." This slide was still largely open in 1956 and 1972 aerial photos, but today only a few small open strips remain. The revegetation on this slide is 99% red spruce.

The upper end of the open strip still provides a nice view of Mount Osceola and Mount Moosilauke beyond a shoulder of Scaur Ridge.

Tracks on the slide track. There was a deep, solid crusty base under a few inches of powder.

 

Looking up from the bottom of the open strip.

Here, for the first time, I found a single forlorn white pine on this slide.

The slide I visited is the second from the left in this 1910 photo by Edward H. Lorenz. Note how vast both the main North Slide and its East Fork were back then, 25 years after they fell.

Following my tracks back down the slope. One of the perks of winter bushwhacking is no need for navigation on the return trip (unless it's extremely windy and your tracks are obscured).

Back at the base of the East Fork, the sun still illuminating the upper slopes of North Tripyramid.

Slanting light, late afternoon.

Love those hardwoods!

Homeward bound on Livermore Trail. I noted that the other three hikers had returned to Livermore Trail from the north end of Mount Tripyramid Trail.  So they either went up and down to the summit(s) via the North Slide (!) or retreated partway up the slide.
