One of my favorite dive sites at South Georgia. A vertical rock wall drops to over 25M, sheltered by Macrocystis kelp and heavily encrusted with sponges and bryozoans. A great place to look for nudibranchs and pycnogonids. Water temperature is usually around 33-35F (0.5-1.5C) in November and February.
