Subglacial Meltwater Channels at Cape Jones, Obruchev Hills, Antarctica
Subglacial curved and winding meltwater channels, and Sichelwannen are recorded from Cape Jones in the Obruchev Hills. Such channels, sometimes referred to as P‐forms, may have a variety of origins. After briefly considering the origins, it is deduced that those at Cape Jones were formed subglaciall...

| Summary: | Subglacial curved and winding meltwater channels, and Sichelwannen are recorded from Cape Jones in the Obruchev Hills. Such channels, sometimes referred to as P‐forms, may have a variety of origins. After briefly considering the origins, it is deduced that those at Cape Jones were formed subglacially while the ice surface of the Denman Glacier became lower and bedrock was exposed The presence of water‐laid glacial deposits on the summit of Cape Jones, and lakes on and adjacent to the eastern margin of the Denman Glacier suggests that the sudden release of impounded meltwater was important |
