The middle part of the glacier is bounded on the south by&#160;Beacon Valley.Scott&#160;(early nineties British Antarctic expedition) named the glacier for&#160;Griffith Taylor, geologist and leader of the Western Journey Party of the British Antarctic expedition.Like other glaciers in the&#160;McMurdo Dry Valleys, Taylor Glacier is “cold-based,” meaning its bottom is frozen to the ground below.&#160;&#160;</geographicDescription>
