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.

A topographical map showing the Rembesdalskåka outlet glacier of Hardangerjøkulen ice cap in Norway. Elevation is depicted by gray contours and a colour ramp from dark blue (low) to white (high). Within Hardangerjøkulen, a dashed line denotes the extent of Rembesdalskåka. Across which are several black lines, each one with a year label (from lowest elevation to highest: 1989, 1993, 2000, 1973, 2017, 1991, 1985, 2019, 1966). Around the edge of the ice cap several mountain peaks are labelled. A scale bar in the top right indicates that the whole map is ~20 km across. Several lakes are shown in a dark blue. The title / legend in the bottom left reads: 'Rembesdalskåka Equilibrium Line'.

A map showing the bathymetry and sub-glacial topography across West Greenland. The topography is on a black to dark blue to light blue color ramp. Contours are drawn and 250 m intervals. There are many fjords and islands. Several fjords have regions where the depth is 1000+ m. There is a subtle hill-shade layer on top of the terrain. There are ~30 glaciers marked as small orange crosses, with their names written along side. The names are in Greenlandic, for example: Nunaarsussuup Oqquatungaani Sermikassak, Tassartooq, Sermikassak, Umiammakku Sermiat, Nakkala, and Kangilleq. The map is titled: 'Glaciers of West Kalaallit Nunaat (Greenland)' with the following text below: 'Changes to the Greenlandic language coupled with a history of exploration has led to many glaciers having multiple names. Greenlandic names are typically descriptive, whereas names given during expeditions are often say more about those on the expedition. For example, Rink Isbræ was named in honour of Hinrich Johannes Rink (Isbræ meaning glacier in Danish). Its Greenlandic name: Kangilliup Sermia, can be approximately translated to mean: The Eastern Ice.'

A map of northern Sweden, Finland and Norway. The coastline and border between the three countries has been drawn multiple times and different scales. The 1:110 million scale is much more angular than the 1:10 million scale. Bathymetry is shown off-shore. Lakes and rivers are also plotted along with a few settlements. The typeface of the labels and corresponding legend items mirrors the scale of the data plotted, with a more pixelated font used for the 1:110 million scale data, and a more refined version of the typeface used for the 1:10 million scale data.
Map titled: 'River Catchments of Scotland'. Distance from catchment boundary is shown as hillshaded topography and coloured using a blue-to-white colourmap. Large catchments, such as the Tweed in the Scottish Borders, Tay in Perth and Kinross, and the Spey all appear as large depressions in the landscape with their catchment boundaries appearing as ridges. The sea is depicted with a random scattering of blue-to-white dots.

A 3d model of mountainous terrain showing a sinuous valley with its surrounding peaks. Titled: 'Val di Genova, Parco naturale dell'Adamello-Brenta' credits: 'by:tlohde / Copernicus Global DEM (ESA)' Labelled peaks are: Cima Presanella (3557 m), Monte Mandrone (3283 m), Cima Lancia (2318 m), Crozzon del Diavolo (3018 m), Corno di Lago Scuro (3164 m) & Cimon delle Gere (3016 m)
Map of the British Isles showing the location of extinct volcanoes (unfilled black circle markers). and bedrock fault lines (orange lines). 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'. A few key volcanoes are highlighted: Anton Dohrn Seamount (70-41 Ma); Erlend (58 Ma); Rum (60 Ma); Ben Nevis (299 Ma); Dundee Law (415 Ma); Arthur's Seat (299 Ma); Loch Na Fooey (490 Ma); Mynydd y Dref (450 Ma); Bardon Hill (570 Ma); Warboys (300 Ma); Gurnard's Head (400 Ma)
A simple black and white map with very few features. A single line of longitude at 52°30′ W and one line of latitude at 72°0′ N cross the image. Just north east of their intersection is the text: 'The marine-terminating Salliarutsip Sermia retreated 12 km between 2000 and 2025'. This text is written over two lines; is aligned south-west to north-east and has a gentle curve to it. At either end of the text are two thick black lines, each slightly curved and jagged, representing the terminus positions of the glacier.

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'
A black and white map of Western Europe. The oceans are black, as are the lakes, and rivers. The land is white, with some black stipples denoting the areas of higher ground. Country borders are not shown. Text in the upper right reads: 'From Calais (Fr) --> Orfu (Hu) via: Belgium where it rained; the Netherlands for (second?) breakfast; Germany where it was hot and I filled my thermos with ice cream; Austria for the only proper hill; and into Hungary for a swim in Lake Balaton.' The route taken is shown, along with the elevation profile of the route along the bottom of the image. At the bottom the text reads: '~2100 km / 13 days / 0 punctures' with credits: 'by tlohde / Copernicus Global DEM (ESA) & Natural Earth'
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.
