Copyright © Craig Romano/The Mountaineers Books Big Four Ice Caves
Hikers have been marveling at these frozen spectacles of nature for over a century. Reached by one of the most manicured trails in the Cascades, Big Four's famed ice caves can be enjoyed by hikers of all walks. Formed from cascading water and warm winds hollowing out heaps of avalanche-deposited snow, the caves usually appear by midsummer.
Instead of immediately heading for the caves, take a short diversion right, following a paved path 0.25 mile to the Big Four Picnic Area. This trail was once a rail line and was responsible for delivering thousands of tourists to a grand hotel where the picnic area now sits. From 1921 to 1949, vacationers came to this spot to golf (the flats before you were once a green), paddle (the wetlands you just crossed were flooded), admire the inspiring view of Big Four Mountain (still in front of you), and hike to the base of the ice caves (just like you!). All that remains of the hotel is a chimney. The grounds have reverted to a semiwild state, and the trail has been upgraded to a top-notch walk in the woods. From this trip back in time, follow the main trail toward the ice caves, crossing through bird-bursting wetlands. In 0.25 mile come to a junction. The trail left will return you to your vehicle. For now, continue straight, soon coming to a bridge crossing the South Fork Stillaguamish River. Two hops and a skip beyond, cross Ice Creek by bridge as well. Now on a very gentle grade, wind through open forest. Notice clumps of mountain hemlock, a tree that usually grows at elevations above 3500 feet. Cross Ice Creek once more and emerge at the barren base beneath the north face of Big Four Mountain. Stare straight up sheer 4000-foot walls where avalanches careen down all winter and spring, depositing tons of snow in the shadow of the mountain. Admire the cascades now crashing down those same walls, helping to hollow out the caves. Walk across the fireweed-rimmed rocky flats to get a closer peek at the caves. But don't venture into or onto them-they can collapse at any time. If it's a hot summer's day, cherish the air-conditioned breezes funneling out of the icy catacombs. Note from WTA: Never enter these ice caves, no matter how safe they might seem. In addition to spontaneous collapse, there is high risk in winter from avalanches off the mountain which feed the caves. Not only is there a risk of being in the avalanche zone, but people have been in the caves and then sealed inside by an avalanche. A woman was killed by falling ice in the summer of 1998.
Driving Directions:
From Granite Falls follow the Mountain Loop Highway east for 26 miles to the trailhead, on the right (elev. 1750 ft). Privy available. You can also hike from the Big Four Picnic Area, which is 0.5 mile before (west of) the caves trailhead off of the Mountain Loop Highway. Recent Trip Reports

This is the first year I have done a significant amount of hiking (I am only 16). The dreary days of fall and early winter going to school had left me yearning for the forest. Now it's Christmas vacation and I have two weeks off. Gee, the weather has been unusually calm and clear over this vacation. What should I do' Head for the hills!

What a difference a day makes! Arrived at the picnic area just when the sun theoretically set on Sunday and decided to go up to see the ice caves instead of attempting to drive to Darrington in the snow. The trail is in good condition except for the 0-4 inches of snow from the bottom to the top and occasional mud spots. Never seen the ice caves before, but it was quite awesome being in the large bowl with all the light reflected off the snow. We stayed well away from the caves and listened to and watched the avalanches for a few minutes before heading back through the dark woods. Reccomended, but may be buried in snow next week.

If you plan your hikes based on a ""breath-taking scenes per mile"" ratio, and don't want to hike to far, this trail is for you. The trail is only one mile long, the elevation gain a paltry 250 feet, but the end is magnificent; a firm snow field, ice caves, and the towering walls of Big Four.

We started the Big 4 Ice Caves hike around 10:40am. The trail was easy to walk, and soon when we got to the ice caves there was nobody there. The ice caves were very interesting. We checked out the edge of some of the caves and went in there just a little. Then we further explored the area and walked to the last cave, where we could see that a big chunkc of ice had collapsed at the end of the cave (next to the rock). It was obviously dangerous to go in these caves.

The trailway is well packed, mostly by snowshoers, and easy to follow. The snow load on the bridges is incredible. The main bridge over the South Fork Stilliguamish is piled six feet above the top of the handrails. That's almost 10 feet of snow along the entire length of the bridge! The bridge is nearly 100 feet long and about 4 feet wide, so the total volume of snow on the bridge is about 4000 cubic feet. This is equal to 6,912,000 cubic inches, but one gallon is equal to 231 cubic inches so that's 29,922 gallons. Now water weighs about 8.3554 lbs/gallon at 4°C under one atmosphere (760 mm Hg), but since this is snow and not water the density is some what less because of air pockets. If we estimate the density to be about .6321 of water, then that's a total of 158,031.5 pounds or 79 tons. That's equal to 29.85 Chevy Suburban LT 4x4s. Golly! |
