Controls of climate and fluvial thresholds on stream incision on the Hawaiian Islands   Open
The extent that climate impacts erosion has long been debated and is difficult to decipher, as climate signals are often obscured by tectonic signals. The Hawaiian Islands are excellent settings to test these relationships, as they have no…

Influence of Lithology and Biota on Stream Erosivity and Drainage Density in a Semi‐Arid Landscape, Central Chile Open
Drainage density is a fundamental landscape feature that determines the length scale for hillslope sediment transport and results from the competition of diffusive hillslope and advective stream incision processes, whose efficiencies are k…
Cosmogenic signal of the stream boulder cover effect  Open
Boulders are ubiquitous in bedrock river channels, moving only when the discharge and slope are large enough to transport them; as a result, large boulders in river channels may retard stream incision by blocking the erodible surface of th…
The story of a summit nucleus: hillslope boulders and their effect on erosional patterns and landscape morphology in the Chilean Coastal Cordillera Open
While landscapes are broadly sculpted by tectonics and climate, on a catchment scale, sediment size can regulate hillslope denudation rates and thereby influence the location of topographic highs and valleys. In this work, we used in situ …

Exploring lithological controls on drainage density in Santa Gracia, Central Chile Open
The controls of drainage density remain a mystery, despite it being a fundamental attribute of landscape morphology. Studies have shown that dry climates with less vegetation or less-consolidated sediment often have higher drainage densiti…

Glaciers are for girls: the inaugural expedition of Girls on Ice Austria succeeded in empowering nine young women in August 2021 Open
Girls on Ice Austria, an organization that encourages young women to stretch themselves through wilderness and glacier travel, camping, science and art, successfully completed their inaugural expedition in August 2021. Nine girls from Aust…
A tale of two plutons: Compositional control on weathering, erosion, and landscape morphology Open
While lithological differences are well known to affect the morphology of landscapes, less is understood about how subtle differences in the composition of granitoid bedrock may affect weathering, erosion, and landscape evolution. Here, we…
Patchy bedrock explained: Tectonic fracture control on landscape evolution patterns in south-Central Chile  Open
Rock fracturing induced by tectonic deformation is thought to promote faster denudation in more highly fractured areas by lowering grain size and directing the flow of water. That the density and pattern of fractures in a landscape play a …

Cordilleran Subduction Initiation: Retroarc Timing and Basinal Response in the Inyo Mountains, Eastern California Open
Subduction zones drive plate tectonics on Earth, yet subduction initiation and the related upper plate depositional and structural kinematics remain poorly understood because upper plate records are rare and often strongly overprinted by m…
Volcanic record of the arc-to-rift transition onshore of the Guaymas basin in the Santa Rosalía area, Gulf of California, Baja California Open
The Gulf of California is an archetype of continental rupture through transtensional rifting, and exploitation of a thermally weakened arc to produce a rift. Volcanic rocks of central Baja California record the transition from calcalkaline…
Provenance of Pennsylvanian–Permian sedimentary rocks associated with the Ancestral Rocky Mountains orogeny in southwestern Laurentia: Implications for continental-scale Laurentian sediment transport systems Open
The Ancestral Rocky Mountains system consists of a series of basement-cored uplifts and associated sedimentary basins that formed in southwestern Laurentia during Early Pennsylvanian–middle Permian time. This system was originally recogniz…
