Ten Thousand Miles with a Dog Sled | Page 7

the lumps of ice with their teeth; but, inasmuch as they usually feel conscientiously obliged to eat each lump as they pull it out, it takes much longer, and in a short daylight there is little time to spare if the day's march is to be made.
[Sidenote: "OVERFLOW" ICE]
We found overflow almost as soon as we reached the Chatanika River, and in one form or another we encountered it during all the two days and a half that we were pursuing the river's windings. At times it was covered with a sheet of new ice that would support the dogs but would not support the sled, so that the dogs were travelling on one level and the sled on another, and a man had to walk along in the water between the dogs and the sled for several hundred yards at a time, breaking down the overflow ice with his feet.
At other times the thin sheets of overflow ice would sway and bend as the sled passed quickly over them in a way that gives to ice in such condition its Alaskan name of "rubber-ice," while for the fifteen or twenty miles of McManus Creek, the headwaters of the Chatanika, we had continuous stretches of fine glare ice with enough frost crystals upon it from condensing moisture to give a "tooth" to the dogs' feet, just as varnish on a photographic negative gives tooth to the retouching pencil. Perfectly smooth ice is a very difficult surface for dogs to pass over; glare ice slightly roughened by frost deposit makes splendid, fast going.
Eighty-five miles or so from Fairbanks, and just about half-way to Circle, the watercourse is left and the first summit is the "Twelve-Mile," as it is called. We tried hard to take our load up at one trip, but found it impossible to do so, and had to unlash the sled and take half the load at a time, caching it on the top while we returned for the other half.
It took us half a day to get our load to the top of the Twelve-Mile summit, a rise of about one thousand three hundred feet from the creek bed as the aneroid gave it. In the steeper pitches we had to take the axe and cut steps, so hard and smooth does the incessant wind at these heights beat the snow, and on our second trip to the top we were just in time to rescue a roll of bedding that had been blown from the cache and was about to descend a gully from which we could hardly have recovered it.
This summit descended, we were in Birch Creek water, and had we followed the watercourse would have reached the Yukon; but we would have travelled hundreds of miles and would have come out below Fort Yukon, while we were bound for Circle City. So there was another and a yet more difficult summit to cross before we could descend the Yukon slope. We were able to hire a man and two dogs to help us over the Eagle summit, so that the necessity of relaying was avoided. One man ahead continually calling to the dogs, eight dogs steadily pulling, and two men behind steadily pushing, foot by foot, with many stoppages as one bench after another was surmounted, we got the load to the top at last, a rise of one thousand four hundred feet in less than three miles. A driving snow-storm cut off all view and would have left us at a loss which way to proceed but for the stakes that indicated it.
The descent was as anxious and hazardous as the ascent had been laborious. The dogs were loosed and sent racing down the slope. With a rope rough-lock around the sled runners, one man took the gee pole and another the handle-bars and each spread-eagled himself through the loose deep snow to check the momentum of the sled, until sled and men turned aside and came to a stop in a drift to avoid a steep, smooth pitch. The sled extricated, it was poised on the edge of the pitch and turned loose on the hardened snow, hurtling down three or four hundred feet until it buried itself in another drift. The dogs were necessary to drag it from this drift, and one had to go down and bring them up. Then again they were loosed, and from bench to bench the process was repeated until the slope grew gentle enough to permit the regulation of the downward progress by the foot-brake.
[Sidenote: "SUMMITS"]
The Eagle summit is one of the most difficult summits in Alaska. The wind blows so fiercely that sometimes for days together its passage is almost impossible. No amount of trail making could be of much help, for the snow smothers
