Gilbert Spur (Bulgarian: рид Гилбърт, ‘Rid Gilbert’ \'rid 'gil-b&rt\) is the mostly ice-covered ridge extending 3.9 km in north–south direction, 2.3 km wide and rising to 1791 m[1] at the confluence of Bender Glacier and Nimitz Glacier, in the southern part of Sentinel Range in Ellsworth Mountains, Antarctica.
The peak is named after Joseph Gilbert (1732-1821), Master of HMS Resolution during the 1772-75 exploration voyage of James Cook, who, along with William Hodges, produced the first paintings from the Antarctic region.
