In the Hindu Kush Himalayas, rock glaciers are becoming important water reservoirs in addition to glaciers, but climate warming increases their hazard potential. Baral et al.’s #newarticle reviews decades of research on these cryospheric landforms: www.tandfonline.com/doi/full/10....

Figure 1. Spatial distribution of rock glacier studies across the HKH, categorized by publication period (before 2000, 2000–2010, 2011–2020, and after 2020). The background shading indicates modeled permafrost probability (Obu et al. Citation2019). Major river basins in the region are outlined, providing the major river basin context for the spatial distribution of existing studies.

A map of the Hindu Kush Himalaya (HKH) region displays the spatial distribution of rock glacier studies categorized by publication periods: before 2000, 2000 to 2010, 2011 to 2020 and after 2020. The map includes major river basins such as the Indus, Ganges, Brahmaputra and others. The background shading indicates modeled permafrost probability. Symbols represent study periods: red for before 2000, purple for 2000 to 2010, green for 2011 to 2020 and blue for after 2020. Recent studies after 2020 are concentrated along the Himalaya and Tibetan Plateau. The HKH boundary is outlined and river basins are marked with blue lines. The map highlights a higher concentration of studies in the Western Himalaya compared to the Eastern region.

In a #newarticle from Hazuková et al., the team collected sediment cores from a lake in the Swedish Arctic and explored the variability in Fe-OC interactions, which likely contribute to shaping OC quality, but not quantity, in Arctic lake sediments: doi.org/10.1080/1523...

Figure 1. Vertical sediment geochemical properties across the three cores collected in a deep (crimson), intermediate (black), and shallow (gray) zone of lake BD03. Panels show A) Organic carbon (%) B) C:N, C) δ13C stable isotope, and D) the Rp index that represents thermal lability of organic C. Due to insufficient material for analysis, a 3–4 cm sample from the deep core is missing from panels A-C.

Image A: Line graph with ′OC percent′ on x-axis and ′Depth (cm)′ on y-axis (0-14 cm). X-axis: 6, 8, 10, 12, 14, 16. Deep series rises from 7 at 14 cm to 12 at 0 cm. Intermediate peaks at 13 near 0 cm. Shallow peaks at 15 near 0 cm. Image B: Line graph with ′C:N′ on x-axis and ′Depth (cm)′ on y-axis (0-14 cm). X-axis: 10, 12, 14, 16. Deep series 11.5 to 14.5, peaking near 0 cm and 10. Intermediate peaks at 15 near 0 cm. Shallow peaks at 16 around 4 to 8 cm. Image C: Line graph with ′δ13C (‰)′ on x-axis and ′Depth (cm)′ on y-axis (0-14 cm). X-axis: -30.0, -27.5, -25.0, -22.5, -20.0. Deep series near -29 to -28. Intermediate near -27.5 to -26.5. Shallow near -22.5 to -20.5, least negative near 0 cm. Image D: Line graph with ′Rp Index′ on x-axis and ′Depth (cm)′ on y-axis (0-14 cm). X-axis: 0.2, 0.3, 0.4, 0.5, 0.6, 0.7.

A #newarticle from Kluetmeier et al. identifies 41 active/transitional and 20 inactive rock glaciers using Sentinel-1 radar data in the La Sal Mountains, Utah: doi.org/10.1080/1523...

This figure depicts La Sal Mountain rock glaciers’ deformation, structure, and morphologies. Panel (a), a schematic displacement-depth plot, is a line graph that shows how displacement varies with depth in a rock glacier. Displacement is greatest near the surface and decreases with depth. Two internal zones are labeled: a secondary shear horizon (shallower) and a primary shear horizon (deeper), with arrows indicating displacement magnitude. Below the primary shear horizon, the rock glacier undergoes plastic deformation with minimal shearing. Panel (b) is a Conceptual Cross-Section of a rock glacier. This side-view diagram of an active rock glacier shows its internal structure. The body originates beneath a steep headwall and extends into an accumulation area. A dashed line marks the shear horizon running near the base of the glacier body. The interior is labeled plastic deformation, and the coarse, blocky texture of the rock glacier surface is illustrated schematically. Panels c-j feature satellite images of active and relict rock glaciers in various forms, including tongue-shaped and lobate, with talus-connected and debris-mantled types.

Disjunct populations of arctic and alpine plants are more affected by macroclimatic variables than localized site conditions according to a #newarticle from Hillman and Nielsen, whose research was based along Lake Superior’s north shore: doi.org/10.1080/1523...

The map of Lake Superior shows depth variations and specific site locations. Depth is categorized into five ranges: 0-10 m, 11-50 m, 51-100 m, 101-200 m and >200 m. The deepest areas (>200 m) are centrally located, while shallower regions (0-10 m) are near the shore. Site locations are marked with dark red circles, primarily along the north-central to north-east shore, including Rossport, Schreiber, Terrace Bay, Marathon and Montreal River Harbour. Temperature loggers are indicated by orange triangles, located at Wawa and Montreal River Harbour. Protected areas are shaded, with Pukaskwa National Park highlighted. An inset map shows the broader geographic context of Lake Superior in North America.

Beason et al.’s #newarticle examines recent studies of Mount Rainier and emphasizes the importance of using long-term data sets and distinguishing between ice-surface and bedrock elevation, as well as provides recommendations for future studies: doi.org/10.1080/1523...

The map shows Mount Rainier's summit crater, highlighting the Columbia Crest Glacier in the east and the bedrock summit on the southwest rim. The ice-surface summit at Columbia Crest is marked with an elevation of 4,387.47 ±0.04 m (14,394.6 ±0.1 ft). The bedrock summit is noted with an elevation of 4,391.04 ±0.04 m (14,406.3 ±0.1 ft). Contour lines indicate elevations, with values such as 14,000 and 14,200 ft. Surrounding glaciers include Winthrop, Emmons and Ingraham. A scale bar indicates 100 meters. The map includes a location inset showing Mount Rainier National Park in Washington. The background imagery is from USDA NAIP with LiDAR-derived contours from 2007–2008.
