The Heart Mountain landslide of northwest Wyoming is the largest known
sub-aerial landslide on Earth. During its emplacement more than 2000 km3 of Paleozoic sedimentary and Eocene volcanic rocks slid >45 km
on a basal detachment surface dipping 2°, leading to 100 yr of debate
regarding the emplacement mechanisms. "Even I have a hard time visualizing a mountain moving 50 kilometers, but you can move it if the friction is low enough," said lead
study author Tom Mitchell.
Despite a well-documented ~40% decline in summer Arctic sea ice extent
since the late 1970’s, it has been difficult to estimate trends in sea
ice volume because thickness observations have been spatially incomplete
and temporally sporadic. While numerical models suggest that the
decline in extent has been accompanied by a reduction in volume, there
is considerable disagreement over the rate at which this has occurred.

The Rock & Ice Physics Laboratory (RIPL) at UCL is a major research facility which forms part of the Earth Sciences Department. RIPL has over 15 members and consists of 11 laboratories, housing over £4M of research equipment., supported by over £2 million of current peer-reviewed funding. The Rock & Ice Physics Laboratory has a unique breadth of experience and ability to design and build its own experimental apparatus.
We study the physical behaviour of ice and rocks that make up the surface and interior of the Earth, and other solid bodies in the solar system, so as to constrain the dynamic, tectonic and environmental processes of planetary evolution. Our research is nationally unique and multi-disciplinary, being based on experiment and theory.
