My own view of the valley was hasty, superficial and from a respectful distance! I can well appreciate, however, what the Expedition endured in order to give to the world knowledge of this wondrous spot. I heartily commend to the readers of this volume the report of Prof. Griggs in the National Geographic Magazine for May, 1917, in which he relates the experience of himself and his party as they made their way back and forth, plunging through suffocating vapors, trapping gases for chemical analysis, making soundings, mapping the course of the valley and studying the geology of what he calls "the most amazing example of her processes which Nature has yet revealed to twentieth century man,—one of Vulcan's melting pots from which the earth was created." In a tent less than two miles from one of the huge clouds of steam he slept at night and on one of the large flat stones outside, so hot that it was a natural stove, the members of the Expedition cooked their food.
One gets the best idea of the magnitude of the valley by comparing it with our Yellowstone Park. The Katmai valley is thirty-two miles long, about two miles wide and seventy square miles in area. In the Yellowstone are four thousand hot springs and a hundred geysers scattered over three thousand square miles. The geysers occur in isolated basins the total area of which is hardly twenty miles. The largest one, and it plays but seldom, shoots up a column about three hundred feet high. Old Faithful, which is the only one the tourist can ever be sure of seeing in action, is only a hundred feet high. In the Alaskan valley, however, observe the contrast. There are thousands of vents in constant action. Some of these ascend more than five thousand feet into the air when conditions are good and when the valley is wind-swept they creep along the ground for two or three miles! These vents are not geysers. They are hot springs. Geysers can exist only when the rock through which they break is sufficiently cool to permit water to form. It is unlikely therefore that there will ever be geysers here,—at least not for many centuries. The valley may gradually cool so as to permit their formation. But it will be ages hence.
Prof. Griggs is emphatic in his belief that there is nothing known to mankind with which "The Valley of Ten Thousand Smokes" can be compared. I agree with him. Would that it were more accessible to the traveler and that no tourist would return from a sojourn in Alaska without seeing it! I shall never cease to be grateful that a fortunate circumstance permitted me to obtain even so small a peep at it. Surely nothing approaching it has been seen by man upon this earth. The Expedition report states, among other interesting things, that the water is so hot that the thermometer would not register it and that the heat from the stones would char a piece of wood instantly!
Kilauea, in Hawaii, has always borne the reputation of being king of volcanoes. It is now dethroned. Mention has already been made of Mt. Shishaldin, on Unimak Island. As no geographer has ever visited it, little is known about it. Katmai, however, is unquestionably the monarch. Not so much in diameter, circumference or area does it exceed Kilauea. It is in depth. Kilauea's greatest depth is five hundred feet. Katmai's is thirty-seven hundred feet!
In an attempt to give some idea of the magnitude of Katmai, I quote once more from Prof. Griggs' report:
"If every single structure in New York, Brooklyn, the Bronx and the other boroughs of Greater New York were gathered together and deposited in the crater of Mt. Katmai," he says, "the hole that remained would still be more than twice as large as that of Kilauea." The king is dead. Long live the king—of volcanoes!
From the glaciers and the mountains of Alaska to the rivers is but a natural turn. One of the most important factors in the life and commercial development of a country is, of course, her river navigation. Alaska has two great gateways to Bering Strait,—the Yukon and Kuskokwim rivers. Until recently only the Yukon was available for commercial purposes, but the United States Coast and Geodetic Survey has announced that at last a channel has been charted through the delta of the Kuskokwim. This means much. It means that a River of Doubt has become a River of Promise!
Because of the latitude at which they enter Bering Sea the Yukon is navigable for three and a half and the Kuskokwim for four months only. The entrance of the Yukon is shallow, that of the Kuskokwim tortuous and not well known. But once inside, an ordinary river boat can navigate the Yukon to White Horse, in Canada, a distance of twenty-two hundred miles. In spite of the short seasons the possibilities of using the river in the development of the valley are apparent and will suffice for some time to come. Navigation is also fairly good on the lower Copper River, the Kobuk, and smaller streams. When it comes to the most winding and tortuous watercourse I have ever encountered, however,—respectfully I salute the Iditarod! One's supply of adjectives, however ample under ordinary circumstances, fails him completely when he attempts to do justice to the crookedness of this river. It writhes and twists and turns like some huge serpent, and when it can think of nothing else to do it doubles back on its own track! To try to follow it would give a man delirium tremens, and like Tennyson's brook it "goes on forever!"
The Pacific coast line, including the Aleutian Islands, has many excellent harbors. With the exception of Cook Inlet, these are open to navigation from November until June, but the ice pack does not extend far south of St. Lawrence Island. This part of the coast is almost without harbors. The Arctic Ocean is open from July to September, permitting navigation to Alaskan ports.
There is cable communication between Seattle and certain parts of southeastern Alaska,—Cordova, Valdez and Seward. Telegraph lines run from Valdez to Fairbanks and down the Yukon to St. Michael from which point there is wireless communication with Nome. These are all military lines. The Navy Department maintains wireless stations at Kodiak and Unalaska. The War Department has wireless stations at Sitka, Cordova, Fairbanks, Circle, Eagle and Nulato. There are also private wireless stations at Iditarod and on Bristol Bay and many of the mining districts are now provided with telephone lines.
