This is a seven antenna Synthesis Telescope. The antennas are all mounted on rail tracks that appear to be straight but are, in fact, curved to match the curvature of the earth's surface.
Here you can just barely make out the Dominion Radio Observatory at White Lake...just around the corner from Green Lake. Boy, someone really stretched it when naming these lakes!
We love Hawthorne Mountain Winery. It is on the Green Lake Road on the road between road between Okanagan Falls and Oliver...a windy, narrow road, but really worth the drive.
