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 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 map showing portions of Cherokee County, Buena Vista County and Pocahontas County. The county borders are straight vertical lines dividing the scent into three even squares. The terrain is depicted with a hill shade and the stream network is shown faintly in black. As one moves east the density and extent of the stream network diminishes rapidly
