The medial moraine is the double line of debris running down the centre-line of the glacier. Lateral moraines can rise up to 140 meters (460 ft) over the valley floor, can be up to 3 kilometers (1.9 mi) long, and are steeper close to the glacier margin (up to 80 degrees) than further away (where slopes are typically 29 to 36 degrees).

The brown lines on the ice are moraines—areas where soil, rock, and other debris have been scraped up by the glacier and deposited at its sides. Where two glaciers flow together, the moraines merge to form a medial moraine. Glaciers that flow at a steady speed tend to have moraines that are relatively straight.
The name and specific characteristics of a moraine are dependent upon its location relative to the glacial body and the processes that deposited the relevant glacial till. [7] Four overarching types of moraines include lateral, medial, ground, and end. The size of the deposited sediments which form a moraine can range from clay to boulder sized.
Lateral moraine on a glacier joining the Gorner Glacier, Zermatt, Swiss Alps. The moraine is the high bank of debris in the top left hand quarter of the image. Glaciologist Erin Pettit in Antarctica, 2016. Glaciology (from Latin glacies 'frost, ice' and Ancient Greek λόγος 'subject matter'; lit.
The characteristically dark medial moraine, situated almost in the middle of the glacier, runs protracted in two bands from the Konkordiaplatz along the whole length to the glacier's toe-zone. This medial moraine is collected from the ice of three large ice fields, which all run together.
A medial moraine in Humboldt Graben, originating near Zwiesel Mountain and trending north in string-like fashion for 13 nautical miles (24 km; 15 mi) along the west flank of the Petermann Ranges. First plotted from air photos by GerAE, 1938-39. Remapped by NorAE, 1956-60, and named Vestbanen (the west path).
