Winter trailside observations

Here’s an assortment of winter observations that gave pleasure to some trail-walkers.

 

• Late November, Eaglecrest. Parks and Rec hikers on snowshoes went up the road, but the majority decided to go home for lunch. Two of us went on, over toward Hilda Meadows, and perched on a log for a snack. Too busy feeding our faces for a few minutes, we eventually began to notice what was around us. Right behind our comfortable log was a big spruce tree with two lumps at the very top. The upper lump was pretending to be a moss wad, while the lower one was eating spruce needles. Both young porcupines were very wet, but the lower one suddenly roused up and rapidly shook itself dry—moving faster than I’d ever seen a porcupine move. The upper one slept on.

• Late November, Mendenhall Lake beach. A small stream flowed over the beach, creating a little opening in the ice. Three eagles were bickering over the remnants of a salmon carcass, which was probably fairly fresh (judging from the bright red blood stains on the ice). We often see late-spawning coho in the streams that feed the upper Mendenhall (years ago, in December, I counted over a hundred eagles on the stretch of Dredge Creek below Thunder Mountain; they were there because the creek was full of coho). One of the eagles snatched up the tail piece and flew off, hotly pursued by a pirate that eventually won the tasty morsel.

• Mid-December, Eaglecrest. Lovely soft snow covered the ground, so animal-tracking was really good. Shrews had been very busy, running over the snow from one bush to another. Lots of other mammals had been active, too: deer, weasel, hare, porcupine, red squirrel, and mouse. Sadly, we found no ptarmigan tracks at all.

• Mid-December, Dredge Lakes area. After a deep freeze, a warm spell had melted ice cover and opened up some of the ponds, and beavers had become active. There were new cuttings in the woods, new twigs in the winter caches, and some of the perpetrators were repairing their dams. The Beaver Patrol was called out of its own winter torpor to make notches in a few dams, lowering water levels in certain ponds so that nearby trails were dry , permitting passage of any late-spawning coho and allowing juvenile salmon to move up and down stream if they chose to do so.

• Late December, Mendenhall wetlands. ‘Twas a very uneventful walk in a blustery wind. But suddenly two small birds blew (not flew!) in and tumbled into the grass. Righting themselves, they revealed themselves as a pair of gray-crowned rosyfinches, a species I’ve seen in upper Glacier Bay and on Mt Roberts, but not out here. That turned the day into a “plus.”

• Late December, Dredge Lakes area. Very low temperatures had refrozen almost all the ponds and streams. However, the ditch from Moraine Lake to Crystal Lake had a couple of very small ice-free patches. And there we saw a dipper, bobbing in and out of those dark pools, no doubt very hungry.

Any sensible dipper would go downstream, perhaps to an estuary, where bugs and fish would be more available!

• Early January, Herbert River trail. A mink had coursed along the elevated riverbank, in and out of the brush, occasionally down to the water’s edge. A set of extremely large moose tracks crossed the trail. That long-striding giant was really moving—the foot prints were often five feet apart. The trackway led through brush and over the arching branches of a fallen tree—almost four feet above the ground. Those long legs! I would have loved to watch that beast (from a respectful distance)!

• Early January, Perseverance trail. Recent heavy rains had brought down some small landslides, not unexpectedly. Unlike the trails near the glacier, this one was nearly clear of ice, and walking was easy. There was fresh snow on the ground, up past Ebner Falls, showing up a few porcupine tracks and some very recent red squirrel trackways. A mouse had crossed the trail with big jumps several times its body length, leaving clear footprints as it hustled into cover across the open trail. I like seeing mouse tracks, in part because I don’t see them very often.

• Mid-January, Switzer Creek area. Before the predicted rains and rising temperatures wrecked the lovely fresh snow, we found tracks of deer, porcupine, possible coyote, and a few mysteries. A shrew had scuttled across the soft snow, making a narrow groove marked by its tiny feet. A good find was a trackway of a grouse, striding through the snow and under low-hanging bushes in the woods. This took a few minutes of searching to determine the track-maker, because the new snow was so soft that it often fell down into the tracks, obscuring the prints. But finally we found good marks of three avian toes.
