Basalt Lake
Basalt Lake is a small freshwater lake surrounded by three basalt outcrops with ‘organ-pipe’ formations in their rocks, situated in the central part of the ice-free Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica. and draining through a 1.6 km stream southwards into Bransfield Strait.
The feature is descriptively named from the surrounding rock formations.
Location.
Basalt Lake is centred at which is 4.07 km northeast of Sealer Hill, 1.85 km east of Usnea Plug
Lake Superior, one can see the solidified lava (igneous rock) most everywhere. In the Rove region the magma didn't reach the surface; it intruded into fractures in the formation and slowly cooled to become diabase (rather than basalt). These solidified bodies are the Pigeon River and Logan Intrusion diabases.
The continent didn't split into two because the Grenville province (a microcontinent) was converging with the proto-North American continent to the east. This convergence applied compressional forces to the rift, preventing the complete
