Little-known UFO crash in Northern Canada in 1960

Did a UFO crash in Clan Lake?

It’s been 50 years since the RCMP investigated a report that something unusual fell into Clan Lake, 30 miles north of Yellowknife. Documents have been made available on the website of the National Archives of Canada that show the RCMP and RCAF were both curious about what happened on June 22, 1960.

The first of six official documents about the incident is available here:

Witness testimony described an object that apparently fell from the sky just offshore. When it reached the water, it looked like a rotating object with “arms or spokes” splashing water in all directions.

When the area was investigated, a narrow channel had been formed in the reeds, but nothing was found underwater when probed with long pieces of wood.

A write-up about the incident is given on this webpage:

National Defence said there had not been any space object tracked in the area and therefore it was not a piece of rocket or satellite. A scientist with the National Research Council of Canada believed the object was a meteorite that was very hot from entering the atmosphere and thus sent up a cloud of steam when it hit the lake. It was suggested that this steam would have been misinterpreted as an object with spokes and water being throw off. The witness’ testimony contradicts this explanation, however.

Here's the thing: meteorites are not always hot when they reach the ground. Furthermore, any meteorite large enough to cause such a big splash and create a channel in the lake bed would certainly have been of interest to the meteoriticists in the National Research Council. Yet the follow-up to the case just fizzled out.

Quite odd.

So, 50 years later, the question remains: what fell into Clan Lake in 1960?
