QUOTE I'm surprised that no-one here has seriously grappled with the relative elevations. Here is an attempt using a DTM from HRSC data (H3198_0001_DT4.IMG), blended with the nadir view (H3198_0001_ND4.IMG). The hypothetical shoreline in shown in white. It is more or less equivalent to the -1480 m contour (estimated from Google Mars because I introduced some sort of offset during file convertion). I canīt find a contour that completely surrounds the hill in question, but that may be because of the resolution of the DTM. Still, this contour line implies a maximum depth of about 410 m for the lake, and some lagoons along the east rim (anyone want to look for shorelines?). Also, at this lake level the hypothetical lake would just begin to spill into a large basin to the southeast (along the red arrow; the contour lines begin to connect if the lake level is just a few meters higher). If the lake really spilled in that direction, I would expect to see some channels; but at a quick glance I donīt see any. EDIT: Used the correct data set now and changed attachment accordingly. |
