Actually, Clarke was referring to what looks like banyan trees. There is a picture at http://www.space.com/science....-1.html

The MSSS site has data about the sun's angle of incidence, etc., that can be used to estimate the height of these "trees" from shadow length. Using some simple trigonometry and rough estimates of distances I calculated that they are at least 300 feet high (close to 100 meters).
I haven't heard any good explanation of what these things are, but I'm all for using Occam's razor... the simplest explanation that fits all the data is the best. They look like trees to me.
