    One of my best (worst) ways to spend some time is to explore remote areas on Google Maps using the satellite view... hopefully there's a street view, or pictures of a restaurant that is 200 miles from the nearest gas station (I found one gas station where it is MANDATORY to fill your car up before you travel further north due to the desolation).

    Anyway, I found this just now. Cool! Any guesses as to what it is? (It's not a trick question)

      It’s a spillway.

        Yeah, carved into ancient volcanic rock, the "staircase" is to prevent erosion when the dam has to release excess water.

          I guess I've started threads like this before, and you're always kind enough to indulge me, LOL. https://nodebb.the-new-coffee-room.club/topic/37597/moar-geography?_=1753798729666

            And people always joke about Minnesota being the "land of 10,000 lakes", which is actually low... we have like 15,000... and folks like @George-K and @Horace know Wisconsin has like 25,000... but Quebec? Over a million, and Alaska has over 3 million lakes!

                This image appears to show a massive stepped spillway or canal channel carved into bedrock, likely associated with a hydroelectric dam or water control structure. The tall structure at the far end looks like a dam with sluice gates, which would control the release of water from a reservoir upstream.

                The stepped, terraced design and rock-cut sides suggest it’s engineered for high-volume water flow while minimizing erosion — a common design for spillways or tailrace channels in large hydroelectric systems. The structure is currently dry or has minimal water flow, indicating it may be seasonal or undergoing maintenance.

                Thank you for your attention to this matter.
