Utopia Planitia

Most of the North of Mars is covered by a low, flat plain.

As such, there are few Souness GLFs, these being found in the walls of craters.

Here is the area of part of Utopia Planitia, north of the shield volcanoes Elysium Mons and Hecates Tholus.

I had originally titled this 'Elysium Planitia' which is in fact in another location south of the Elysium Mons massif. The URL will continue to reflect that.

Overview

A small number of Souness GLFs are found inside craters in Utopia Planitia.

 Four HiRISE anaglyphs overlap or are in the vicinity of Souness GLFs:

• PSP_007884_2195 (overlapping S198)
• PSP_004192_2195 (within same crater as S198)
• PSP_002214_2210  (in crater Kufra at 120°E, 40.5°N, where there are 4 Souness GLFs found.)
• PSP_002266_2190 (at 137°E, 38.5°N near S193, not covered by a HRSC DTM)

Zooming into the area covered by HRSC tiles h1526 and h2878.

Zooming in further to several areas of interest:

Crater at 116°E, 39°N containing 3 Souness GLFs, with HiRISE anaglyph coverage of one of them. HRSC tile h1526 nadir image with the classifier results.

A crater further north in tile h1526 at 43°N without any catalogued Souness GLFs, though there looks to be remnants of some kind of flow features.

Classifier results show topography favoured for glaciers.
