    I've read several different estimates in the range of 680-840 meters.
    Accurate?
    Your thoughts?

    ...............
    And, if we discount any mountains over 3500 meters in altitude what would the average of the remaining land be?

    Sorry . . . . .won't do YOUR homework for you! . . . . . . but a hint: (mean) geoid value will decrease . . . . . HAHA!

    WOW!! . . . . '680-840 meters average' . . . and Plato, Missouri (USA) is within that range*! AND . . . mysteriously, Plato is also the population 'center' of the USA (last US Census!) . . . . amazing, the Universe certainly seems (IMO) more complex that it really is! . . . . HSIRI . . . .HAHA!

    *Correction: Actually, the elevation of Plato is 1,115 feet (AMSL). I attribute my elevation error to 1) poor memory, or 2) continuing isostatic rebound ongoing during my lifetime (a lot of years!).

    "homework"
    cute

    ..................
    meanwhile:
    Göbekli Tepe (“Stomach Hill“ in Turkish) is a unique archaeological site, beneath massive sediments on a hill at about 750 meters (2460 ft.) above sea level
    ..........................
    meanwhile
    as sea levels rise, the elevation of my house shrinks relative to sea level. fortunately, the relation to the spillway of the downriver dam remains the same.

    ........................
    however
    none of which answers my question

    I guess in the midst of my humor, I failed to understand the basis of your thread. Can you provide the point of your post? Are you concerned regarding possible sea-flooding of the Gobekli Tepe site with a rise in sea level? Sorry for my fail . . . . .

    No concern other than curiosity.

    If you've read some of mine, then it becomes obvious that my interests lie in anthropology and archaeology, zones of human habitation and migration through time, and like that.
    The median for human habitation is about 194 meters elevation, but the average is closer to 120 meters. ........................

    So this question was just another thread in an ongoing weave/web of knowledge.

    Does ice count as rock? Because that's going to affect your average.

    Human beings live near trees, fresh water, and warmth - ideally, on a forested elevation overlooking a body of fresh water surrounded by savannah and not far from a shallow ocean. Technological advance has allowed us to spend increasing amounts of time at increasing distances from that fundamental best situation.

    But the height of trees, fresh water, and warmth matters far more than the height of the rock.
    How is that arithmetically possible, since the outliers are bounded more closely below (at o, or sea level)?
