On a warm, sunny, buggy day I wandered deep into the Sabbaday Brook valley and visited one newer slide and a couple of older ones. The mosquitoes were out in force as soon as I started out from the trailhead.
Emerging onto the base of the slide, where there is a broad deposit area that has been heavily revegetated.
The 1925 edition of the AMC White Mountain Guide noted that either this slide, or the older one just to the south used by the Sabbaday Brook Trail, could be used as a route to the crest of Mt. Tripyramid: "Either slide may be ascended to its tip, with wild and interesting views towards Passaconaway and Chocorua." That vista is still available from the open patch, but may not be for many more years.
On the way back down the valley I made another short bushwhack to the only opening left on the southern of two old slides on the Fool Killer. This slide may date back to the 1910s, as it looks fresh in a photo taken then that can be seen in the online archives of the AMC. When I climbed the Fool Killer in 1998, I used this slide for the start of the ascent, but even then it soon petered out. Such is the fate of many slide tracks in our fast-growing forests.
