Another Canadian wind harp is on the shores of Cape Breton, in Nova Scotia. This wind harp also doubles as the Invalid Link Removed, built to celebrate the city's Celtic past.

Some pictures from the family album.
THis is a picture of the worlds first hydrogen bomb, Ivy Mike, in 1952 at Entiwtok Atoll which was housed in a building becasue it was so large. The detonation was coordinated through a flagship offshore; hence the antenna for radio and tv cameras.
The big vertical metal thing is a dewar flask holding the deuterium isotope of liquid hydrogen at near absolute zero plus the device . The pipes coming off the flask are light pipes to transmit data before the structure is vaporized.
This is a picture from the first device at Bikini Atoll, "Bravo Mike" or "Castle Bravo 1954. The dewar is gone and the device is a lot smaller as they have figured how to use Lithium deuteride instead of liquid deuterium for fusion fuel. Unfortunately, they used about 2.5x times as much fuel as necessary as they didnt realize the "inactive" Li-7 converted over to fusionable Li-6 under neutron bombardment , increasing the yeield significantly. This resulted in a much larger yield and redioactive contamination of the atoll, the surrounding ocean and a japanese fishing vessel. At that time, they used large amounts of uranium as the "tamper" to boost the fusion stage, which made it a very large dirty bomb.
The eight pipes at the right end (1) sent information about the detonation of the primary. Two in the middle (2) marked the time when X-rays from the primary reached the radiation channel around the secondary. The last two pipes (3) noted the time radiation reached the far end of the radiation channel, the difference between (2) and (3) being the radiation transit time for the channel. In hydrogen bombs, synchronization of the stages is critical to high yield.
In the lower right you can see the causeway which supports the light pipes that convey detonation data down to the data bunker about 7500 feet away. Due to the higher yield, the unmanned data bunker was destroyed on this detonation.

Today, Cool Patch Pumpkins in Dixon, CA announced their 2015 corn maze, featuring a 3.5 acre Sacramento Kings logo. The Cool Patch Pumpkin maze is located 20 miles west of Sacramento.

Horsetail Falls is a waterfall in the Sierra Nevada mountain range, to the west of Lake Tahoe in the Desolation Wilderness of El Dorado County, California, United States. It falls in stages for nearly 500ft (150 m). It can be reached by hiking north out of the Twin Bridges trailhead on U.S. Route 50.
The hiking part is about 600 elevation on granite. It’s not a straight up climb. It’s a bit of effort getting up there, but the view is spectacular.

Red Planet Day
We know more about Mars than any other planet but our own. That knowledge has been gained over centuries and has grown exponentially in recent years with the successful landings on Mars of the Curiosity and Perseverance rovers in 2012 and 2021 respectively. Today we celebrate those and other accomplishments on Red Planet Day, which coincides with the launch of Mariner 4, the first probe sent to Mars, on this day in 1964.
Mars was observed in ancient times as a bright and moving object in the night sky, distinct from the stars. Even its reddish tint was observed by the naked eye. Our curiosity was cemented. It might not be the planet closest to ours—Venus owns that title—but it seems to be the planet that most captures our imagination. The more we learn, the more we can imagine that Mars might have been just like Earth a long time ago, possessing organic life, rivers and oceans, and a much thicker atmosphere than it does today. Current conditions on Mars, while not exactly habitable, are hospitable by comparison to those on other planets, may be the most compelling reason we're inclined to imagine that living on the Red Planet might someday be possible.
