This beautiful, old and interesting chart is one of the first geological maps of the USA and Canada (aka British North America), based on actual geological surveys by Professor Henry Darwin Rogers and published by AK Johnston in 1856. Parts of north Mexico can also be seen.
 There's a huge amount of detail on this map - most of the USA's rivers are shown, as are every city and some smaller towns as well. Across the bottom of the map is a cross-section of the Appalachian range, from New Jersey's Egg Harbour to Lake Ontario by the Niagara river.
 Of course, the main feature of the map is that it shows you all of the various geological deposits and their ages, from quaternary to Mesozoic to metamorphic, along with their 'European equivalents'. 
 This map looks great at all sizes: 12x16 inches (30x40cm), 16x20 inches (40x50cm) and 18x24 inches (45x60cm), but it looks even better when printed large. I can create beautiful, large prints of this map up to 70 inches (180cm) wide. Please get in touch if you're looking for larger, customised or different framing options.
 The model in the listing images is holding the 20x16 inch (50x40cm) version of this map.
 I have a couple of similar maps published AK Johnston, of the geology and palaeontology (fossils) of 
Scotland and 
the British Isles.
This would make a wonderful birthday, work leaving, housewarming, Christmas or Father's Day gift for someone from the US, or who has an interest in geology.
 You can order the map itself, or you can order a framed version. The frame is a nice, simple black frame that really makes our maps pop out when on a wall. Please get in touch if you'd like a different frame. We use super-clear acrylic (perspex/acrylite) in our frames - it's less reflective than glass and better for transport.
This map is also available as a float framed canvas, sometimes known as a shadow gap framed canvas or canvas floater. The map is printed on artist's cotton canvas and then stretched over a handmade box frame. We then "float" the canvas inside a wooden frame, which is available in a range of colours (black, dark brown, oak, antique gold and white). This is a wonderful way to present a map without glazing in front. See some examples of float framed canvas maps and explore the differences between my different finishes.
For something truly unique, this map is also available in "Unique 3D", our trademarked process that dramatically transforms the map so that it has a wonderful sense of depth. We combine the original map with detailed topography and elevation data, so that mountains and the terrain really "pop". For more info and examples of 3D maps, check my Unique 3D page.
