Restoration of the dichotomy boundary to its original position to assess its origin requires a thorough knowledge of processes responsible for its degradation and retreat. The unique fretted terrain, located along the Deuteronilus‐Protonilus Mensae northern mid‐latitude portion of the boundary, has been long held to provide clues to dichotomy degradation processes. We use new spacecraft data to show that fretted valleys display a multitude of characteristics typical of integrated valley glacial… 

Evidence for Hesperian glaciation along the Martian dichotomy boundary.

Here we provide geologic and geomorphologic evidence of Hesperian glacial activity along the Martian topographic dichotomy in Aeolis Mensae. Our geologic investigation focuses on a fretted plateau

Lineated valley fill at the Martian dichotomy boundary: Nature and history of degradation

The fretted terrain of the Martian dichotomy boundary is a key region for investigating landforms related to creep of ice and debris as it exhibits landforms comparable to morphologies of periglacial

Hemispheres Apart: The Crustal Dichotomy on Mars

The hemispheric dichotomy is a fundamental feature of Mars, expressed by a physiographic and geologic divide between the heavily cratered southern highlands and the relatively smooth plains of the

Late Amazonian Ice Survival in Kasei Valles, Mars

High‐obliquity excursions on Mars are hypothesized to have redistributed water from the poles to nourish mid‐latitude glaciers. Evidence of this process is provided by different types of viscous flow

Patterns of accumulation and flow of ice in the mid-latitudes of Mars during the Amazonian

Late Amazonian glaciation at the dichotomy boundary on Mars: Evidence for glacial thickness maxima and multiple glacial phases

Lineated valley fill (LVF) in fretted valleys at the dichotomy boundary has been interpreted as glacial in origin. Unknown are (1) the original thickness of the glacier ice, (2) the amount of
