We present a new reconstruction of the Antarctic Ice Sheets between 20 ka BP and the
present day. Our reconstruction is derived using a numerical model to generate a physically …

Reconstructing past variability of the Antarctic ice sheets is essential to understand their
stability and to anticipate their contribution to sea level change as a result of future climate …

The Antarctic Dry Valleys (ADV) are generally classified as a hyper-arid, cold-polar desert.
The region has long been considered an important terrestrial analog for Mars because of its …

We present a glacial record from the western Olympus Range, East Antarctica, that
documents a permanent shift in the thermal regime of local glaciers, from wet-to cold-based …

Thermal contraction crack polygons are complex landforms that have begun to be
deciphered on Earth and Mars by the combined investigative efforts of geomorphology …

Desert landforms are characterized by an abundance of 'bare'rock and mineral surfaces.
Mountains host widespread exposures of bedrock. Gravel desert pavements cap alluvial …

The∼ 166,000 km2 fan‐shaped deposit at Arsia Mons contains three characteristic facies
(ridged, knobby, and smooth), which are interpreted as the depositional remains of a cold …

Erosion rates offer insight on landscape development and the relative importance of
chemical and physical processes of weathering. Minimal chemical weathering makes …

Alteration of fresh rock surfaces proceeds very rapidly in most terrestrial environments so
that initial stages of modification of newly exposed surfaces are quickly masked by …

Abstract The Friis Hills (77° 45′ S, 161° 30′ E), in the McMurdo Dry Valleys region,
Antarctica, is a 1-km-high inselberg with early to middle Miocene–aged glacial deposits …
