The Terra Firma Islands were first visited and surveyed in 1936 by the British Graham Land Expedition under John Rymill.

Hayrick Island was surveyed in 1948 by the Falkland Islands Dependencies Survey and so named by them because, when seen from the east, its high mass has an appearance suggesting a hayrick.

It depends on the San Martín Base north of the refuge 66 kilometres (41 mi) faraway.

The refuge is located on the west coast of the island and owes its name in homage to the Regiment of Mounted Grenadiers that participated in the construction of the refuge.
