Arctic, Antarctic, and Alpine Research is an Open Access international, scientific journal publishing multidisciplinary environmental research on cold regions. https://www.tandfonline.com/journals/uaar20

The map of Alaska shows modeled permafrost zones: continuous, discontinuous, sporadic and the Arctic Circle. B) A detailed map highlights Kotzebue Sound with permafrost zones. C) Satellite image of Baldwin Peninsula with a marked transect area. D) Close-up of the transect area with labels: RTS, M, UL, TL, SDL and DLB. The map illustrates spatial distribution of permafrost types, with continuous zones in northern regions and sporadic zones in southern areas. The transect area is detailed with specific geographic features and labels, indicating research or observation points.
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.
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.
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.
The map shows the position of the CRREL Tunnel in Alaska, near Fairbanks, with major geographic features like the Arctic Ocean and Gulf of Alaska. B) The plan view of the CRREL Tunnel displays the layout with labeled sections: North Tunnel, South Tunnel, Winze, Cross Cuts 1-3 and Gravel Room. Exposure numbers 1 to 8 are marked. C) The photograph captures the interior of the North Tunnel, showing the positions of Exposures 1, 2, 4 and 6, with the Winze visible. The image highlights the tunnel's structure and lighting.
