A dark map of Lake Baikal. Titled: 'Lake Baikal' with subtitle: 'Age: oldest (25-30 million years) Depth: deepest (1,642 m) Area: 7th largest (Belgium + 1,033 km2)'. The bathymetry is coloured from dark black at the deepest through a purple-y gray to gray for the shallow regions. A colorbar has the 'dysphotic' and 'aphotic' zones roughly labelled. It spans latitude 52-56 N and longitudes 104-110 E. (approx). A dark, mostly black, subtle hillshade is applied to the surrounding landscape. The lake cuts a roughly diagonal line from the bottom left of the frame to the top right, and it is very narrow compared to its length.

The coastline is shown in thick black, with a slight dropshadow. The map is coloured in such that the volcanoes are a bright orange/yellow, and the colour moves to a darker purple with distance from a volcano. The same colourscheme is applied at sea, however with reduced opacity. The title text reads: 'The ~~British~~ Volcanic Isles' with subheading: 'Volcanic activity across the British Isles peaked during the Paleozoic (539 to 252 Ma*), with the last significant eruptions occuring during the Paleogene (66 to 43 Ma). *million years ago'.

Map of Wales. Titled: 'Access to the Railways' The map is a proximity surface, with bright colors representing large distances from a railway station, and darker colors closer to train stations. Additionally the proximity surface is shown with illuminated contours giving the a 3d-ish feel, with the railways running along ridges, and places far from the network appearing to be at the bottom of a hill. The middle of snowdonia and a portion of the west coast are shown as being the furthest from the network. An annotation reads: 'Llangrannog the furthest village from a train station (in a straight line)'. At the top right some text reads: 'Platform Wales'. the credits read: 'by tlohde / OpenStreetMap Contributors'
A map of East Anglia, UK. No features have been drawn on the map, however the land is coloured from white to pink to dark pink depending on the depth of superficial deposits. The majority of the region is white, however there are some bands of pink and a few patches of dark pink, neart the Suffolk/Norfolk border. In the top right is a histogram showing the distribution of depths. The frequency is shown on a log-scale, indicating most areas have no deposits, but some have up to 100 m. The title runs downt the right side of the plot and reads: 'Depth of Superficial Deposits East Anglia UK' and is written in white with a large drop shadow in dark pink. The north sea / background is black, which makes the whole image quite high contrast. Credits along the bottom read: 'by:tlohde / ‘Contains British Geological Survey materials © UKRI 2025'

Map titled: 'Qikiqtaq 69°10ʹN 57°25ʹW, Kitikmeot Region, Nunavut, Canada' The island is irregularly shaped, with several larger bays/inlets. The island is covered with many, many lakes. The lakes have been coloured in a variety of blues. In the top left is a small histogram showing the distribution of lake areas, on a logarithmic scale: with mode of 0.01 km^2. In the bottom left is a map showing where Qikiqtaq is in the Canadian Arctic, above the rest of North America and to the west of Greenland. A scale bar in the bottom right corner is 25 km wide, indicating that the whole island is ~200 km across at it's widest point. Some text in upper right reads: 'here, lakes cover ~24% of the island and there are ~46 lakes per person'.
A map titled: Barnes Ice Cap, Baffin Island, Nunavut, Canada. The map is comprised of a Sentinel-2 RGB image satellite image showing the ice cap which is up to 60 km across and in excess of 100 km long. Surrounding the ice cap are mountains, some with snow covered peaks, others rocky, along with many bright blue lakes. Overlaid on top of the ice cap are flow lines indicating the direction of ice flow, and colored according to the speed of flow. The lines clearly show the ice divide in the middle of the ice cap. The color of the flow lines is on a logarithmic scale from 0 to 100 m/yr, as shown in the color-bar beneath the main plot. In the upper left is an inset showing where Baffin Island's position to the west of Greenland, and above the north eastern limit of North America.

A map of western Europe with a handful of different coloured lines across France, Switzerland, Northern Italy, and the Baltic States, and lots of interseting lines in the UK. An inset shows a zoomed in section on central London
On a black background are many many, small wiggly lines, the lines are coloured by the direction in which they go, using a circular colour map. If you know that the lines depict where water would flow over a landscape, and that the colours correspond to the direction, one can see how this does resemble terrain, with lower elevations and river valleys depicted as empty space, and ridges are where the lines of different colours meet. It is messy and quite abstract
a ridgeplot style map, showing the topography of the Parco Naturale dell'Adamello-Brenta, with a smooth colour ramp from pale yellow in the foreground to darker blue in the far-field. Along the right and left edges are names of Rifugi (mountain huts) and lines leading to its location in hills
A satellite image showing a few outlet glaciers in west Greenland. Two are labelled: In orange: Kangaasarssup Sermia (KS) and in blue Isortuarsuup Sermia (IS). An inset shows a close up of the terminus of IS where ice bergs can be seen in the lake.
Three subplots, the two on the left cover the same extent, and the one on the right shows a smaller area contained within. The top left shows change in ice veloicty (green=faster, pink=slower). There is no pink, and the intensity of green increases towards the glacier. In the lower left the rate of surface elevation change is shown where red=thinning, blue=thickening; much of the glacier has thinned with the greatest thinning near the terminus. Two water bodies indicate some increases in elevation, however dh/dt values over water are not to be trusted. On the right, a close up satellite image of a glacier terminus with multiple terminus traces shown for a 6 year 2014-2020 period. Some terminus retreat is visible at the northern end of the glacier, near some grounded icebergs
A map of world showing only 'peaks' from OpenStreetMap. Oceans, and land are black, and peaks are shown in blue, and regions with higher concentration of peaks in a lighter blue nearing white. More than anything this map shows how less populated regions of the world have had far fewer peaks mapped

A map of the Cairngorms national park. Black background with white national park border. Within the national park the terrain is represented by colors ranging from black through dark purples to bright orange. Brighter colours represent regions that are 'more visible' than darker regions, as these areas can be seen from more summits. The resulting sum of viewsheds bears strong resemblance to the underlying topography.
