| Comment |
A collapse scar is not a depression but is marked by vegetation different from the peatland that did not contain permafrost. Irregular topography (hence thermokarst terrain) may be present on the peatland as a whole but the collapse scars are only part of that thermokarst terrain, marked by the absence of permafrost, and by vegetation different from that on both the previously unfrozen peatlands and the remnant permafrost peat landforms.
