    This map bothers me as they omit Lake Tahoe, which is higher than Baikal (~6,200 ft) and deeper than everything except Baikal (~1,600 ft deep)

    What’s the point of including all that empty space between Baikal and Titicaca when there’s a world renowned lake that would be great to include

    Why is lake Baikal the only one with measurements in meters?
    Feels like the map maker made a half-hearted attempt and just gave up after the first one.

    Why bother making this at all if it’s not to scale? Sure, nobody expects the horizontal scale to be the same as the vertical scale. Vertical exaggeration is common when displaying profiles or cross sections, but those are generally still considered to be at a particular scale. But, if the vertical scale isn’t consistent, then what even is the point of the graphic? Just list some numbers in a table. Putting this in graphical form without a consistent scale is just lying and lazy.

      It looks like these are two separate graphics spliced together, everything on the right seems to be to scale (or reasonably close to it)

          The disclaimer doesn’t say it’s inconsistent, though. Just exaggerated, which is good because otherwise everything except maybe Baikal would be a horizontal line.

            It says “not to scale”, which in the world of mapping means very specifically that the scale is inconsistent. An exaggerated vertical scale would not include the disclaimer for “not to scale” and is very common, as I already said. It’s common for maps showing vertical reliefs like profiles or cross sections to have a horizontal scale of something like 1:20 while the vertical dimension has a scale of 1:5 or 1:10, which would still be considered “to scale”. If you still can’t fit everything on a single sheet, you can add a break line or a jog to indicate a discontinuity, but the map would still be “to scale”. This map is “not to scale” because it says so, so the only real information we should be able to glean from it are the connections between things; size, angles, and lengths as are meaningless because that’s what “not to scale” is specifically warning us about.

              I think we actually have to get out a ruler here. In the world of infographics, “not to scale” usually just means one dimension is at a different ratio from the other(s).

                  Then go yell at OP about posting a non-map.

                  There’s no lie here, nobody thought lakes are actually finger-shaped in cross-section.

      Huron and Michigan are hydrologically a single lake because the flow of water through the straits keeps their water levels in overall equilibrium.

      It’s the same body of water, one lake. It’s just massive, and surrounds the lower peninsula of Michigan, so they gave each side of the lake a different name.

      Truly it’s massive, it behaves almost like the ocean in a lot of ways. A lot of water.

        The waves on Lake Michigan were far larger than I expected when I visited. Not as high as the Atlantic or Pacific, but pretty big.

          Right!? I’ve lived here my whole life, so it’s normal for me. But when we had friends in to visit from a coastal state, the waves were big, and they were amazed. They kept forgetting it wasn’t the ocean, and they loved that they didn’t have to rinse off the salt afterwards 😁

        Wow, no way! I thought the part between the UP and LP was a lot narrower than it is! Never realized that it was just one big lake with a narrow part

          Yeah it’s crazy, the Mackinac bridge is like 5 miles long, no foot traffic allowed except for one day of the year when thousands of people get together and walk across it.

    Lots of criticisms but still really cool. I’d love to see one to scale as well (for width and depth)
