During the Klondike Gold rush three aerial tramways and several surface hoists operated over the Chilkoot Pass. Two of the tramways are significant engineering feats. The Chilkoot Railroad and Transportation Company crossed a distance of 2,200 feet in one span, then the world's longest, and the Dyea-Klondike Transportation Company was one of the first aerial tramways powered by electricity. These tramways and hoists were important final links in the chain of developments to make Dyea and the Chilkoot Pass the dominant route to the interior. However, they failed to successfully compete with the White Pass and Yukon Route railroad and most were bought out by the Skagway road.
The Peterson Hoist
[Peterson] anchors a pulley at the top through which he passes a rope, to which is attached a box, rigged on runners. A loaded sled is made fast to the rope at the bottom; the box is then filled with snow, to which is added the weight of the inventor and such other men as may be at hand. When this loaded box descends it pulls the sled up, where it is detached. The box is then unloaded and drawn back to the top when the operation is repeated as before.
In 1894, Peterson had previously attempted to do the same operation with sealskins instead of a box with runners but it failed. He returned in 1896 with the gravity hoist described above. According to a sourdough known only as "Silvertip," Peterson charged four bits a load. On February 17, 1898, he leased his tram to J. F. Hielscher of Dyea for five months, the peak months of the rush. He received a half-cent royalty on each pound carried by the operation.
The exact location of the Peterson tram is unknown. He may, in fact, have operated on the nearby Peterson Pass (which was named after him) instead of the Chilkoot Pass. There are many artifacts in the vicinity of the pass but because of its simplicity, it is difficult, if not impossible to identify the exact line or pulley Peterson used.1

Did You Know?
The Chilkoot Trail was an important trade route connecting the Tlingits with interior First Nation peoples long before the Klondike Gold Rush. Dyea or Deiyaa (Tlingit for "to pack") was a small Native settlement used as a fishing camp and staging area for trade expeditions to and from the interior.
