More from Okanagan Backroads Volume One
Old Fairview: White Lake Observatory
Mile 12.1 (4.4) – Half a mile further along, the access to White Lake Observatory turns right. (White Lake itself is the alkali pond opposite the Twin Lakes turnoff.)
Because of their electrical systems, which interfere with the operation of the radio-telescope, cars are not allowed on the road to the radio telescope. The big dish itself towers above the other installations, listening eternally to signals from outer space. The maze of poles and overhead wiring back towards Oliver are another form of radio-telescope, which pick up very long radio waves. The observatory is well worth walking the three-tenths mile; what's happening is completely incomprehensible to the layman, but fascinating nonetheless.
(1975/77)

This observatory still exists, under the rather grander name of the Dominion Radio Astrophysical Observatory. It is, so the government website tells me, "an internationally renowned facility for radio astronomy and leading-edge instrumentation." Until just now, I had no idea that it existed.
DRAO is still, naturally, a radio-quiet site, which must be more difficult these days than in 1975.
Dave Stewart, author of Okanagan Backroads, is quite right about its fascination. I am absolutely a lay person, and yet statements like this are weirdly thrilling: "The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is Canada's largest radio telescope. ... CHIME has no moving parts, but the Earth's rotation allows the telescope to map all of Canada's visible sky every day. CHIME was designed to survey atomic hydrogen from the largest volume of the Universe to date." No real idea why that would be important to do (feel free to explain!), but I'm glad it's happening here.
They have a Perseids viewing party next week!
