We have mapped 18,000+ circular mounds in a portion of southern Acidalia Planitia using
their sizes, shapes, and responses in Nighttime IR. We estimate that 40,000+ of these …

Two transverse dune fields occur among Late Amazonian volcanic and aeolian landforms in
southwestern Tharsis, Mars. The first is located∼ 70 km northwest of Biblis Patera, around …

We have mapped the area of Isidis Planitia (1–27° N, 75–103° E) in order to assess the
geologic history of this region using modern data sets such as MOLA topography and the …

The role of water in carving the Martian outflow channels has recently been challenged by
the hypothesis known as “White Mars.” This hypothesis claims that the channels were cut by …

We have used data from the Mars Reconnaissance Orbiter to study 30–80m thick light-toned
layered deposits on the plateaus adjacent to Valles Marineris at five locations:(1) south of …

This paper presents the hypothesis that the well-known giant polygons and bright mounds of
the martian lowlands may be related to a common process—a process of fluid expulsion that …

Athabasca and Marte Valles lie on the Cerberus plains, between the young, lava-covered
plains of Elysium Planitia and Amazonis Planitia. To test pre-MGS (Mars Global Surveyor) …

Small edifice features that are less than a few kilometers in diameter and up to a few
hundred meters in height are widely distributed in Chryse Planitia on Mars. They exhibit a …

We report the detection of mound-like landforms interpreted as mud volcanoes within Firsoff
crater, in the Arabia Terra region of Mars. The mounds stratigraphically overlie layered …

Volcanism on Mars occurred until recently, but the mineralogy of recent lava plains is poorly
known because few regions display fresh outcrops devoid of dust. Using visible and near …
