The Miles Canyon Basalts

The Miles Canyon Basalts speak to a bundle of rocks that incorporate different exposures of basaltic magma streams and cones that emitted and streamed over an old pre-frigid scene in south-focal Yukon. The volcanic rocks are best uncovered and most effectively available at the Miles Canyon area where the Yukon River slices through a progression of streams south of Whitehorse. In the spring, great exposures can likewise be seen instantly downstream from the Yukon River hydro dam in Whitehorse which was worked to extricate vitality from the waterfalls that were the White Horse Rapids.

These rapids and the Miles Canyon gave a huge test to gold-searchers making a beeline for the Klondike Gold Rush, and furthermore settled the upstream end for oar wheel waterway vessels. This, the Miles Canyon Basalts are the purpose behind the foundation of the townsite of Closeleigh, in the end the City of Whitehorse. The magma streams and soot cones in the Alligator Lake volcanic complex southwest of Whitehorse are the best amassing of these stones.

The Miles Canyon Basalts were believed to be Pleistocene age. In any case, land examinations bolstered by geochronological investigations show that these stones are significantly more seasoned. The 'type' Miles Canyon streams along the Yukon River are 8.4 million years of age Miocene and the Alligator Lake streams are 3.2 million years of age Pliocene. The Alligator Lake cones might be more youthful yet have been influenced by glaciation so are not so much post-chilly in age.
