Parabolic sand dune formed during the last cold period of the Weichselian ice age (the Late Pleniglacial and Late Glacial). Excess sand caused the river Amer to silt up, creating fords. Hence the name Amersfoort. Location: maps.app.goo.gl/qnF6G3WXDN79...
An elevation model map of a city in the Netherlands (Amersfoort) showing distinct height differences through color gradients.
Waterways and low-lying ground appear in deep black, carving prominent intersecting lines and a large knot-like junction across the right side of the frame.
Higher elevations are rendered in shades of light gray and pale green.
Lower topography on the left and bottom right are highlighted in vibrant, textured greens.
Higher terrain and elevated structures are marked by warm orange and rust tones scattered throughout the urban grid.
A small blue logo reading "HydrologyNL" is located in the bottom right corner.
It shows a brown U-shaped dune.

It was 28.6 °C today (29 September 2026) in the Netherlands. At the premises of @knmi.nl 25.9 °C was measured. This is an extreme deviation of no less than +8.2 °C above the climate average (17.7 °C). Meanwhile the discharge in the River Rhine has never been measured as low as now.

Romania's Oltenian Sahara is an example of anthropogenic desertification. Drainage of lakes and clearing forests since the 1960s has left >100k hectares degraded. The sand expands by 1,000 ha/year, prompting a massive 18,000 ha reforestation initiative.
A detailed digital elevation model (DEM) map capturing the Danube River winding through the diverse topography of southeastern Romania.
The image uses a vibrant color gradient to signify varying elevations, with higher, mountainous terrains in the top and bottom left corners rendered in warm shades of light brown, orange and yellow. These areas transition down into undulating plateaus and lower plains shown in cooler shades of light greenish blue and blue.
Cutting horizontally across the lower third of the landscape is the Danube River, depicted as a stark white, braided ribbon flowing from the left toward the right. The river moves through a wide, deep blue flood plain, emphasizing its lower elevation compared to the surrounding dramatic bluffs and terraced river valleys. In the bottom right corner, a small dark blue rectangle contains the white text "HydrologyNL".

Came across this ~800 square m-large landslide in East Finnmark while mapping. The terrain is dead flat, so it probably reflect that a thin lens/pocket of quick clay in the deep was punctured by the river to the North causing the overlying (glacio)fluvial sands and gravels to be swept away.
