The always interesting urban exploration crew at Trackrunners have assembled all of their various trips down beneath the streets of Barcelona into one long super-post, an epic catalog of all things lost and subterranean in that Spanish coastal city.
Underground, where this is no GPS and certainly no Wi-Fi, mapping caves requires a different kind of technical ingenuity. Thus, there is cave radio. To learn about the DIY world of cave radio and underground exploration, Gizmodo picked the brain of Stanley Sides, tinkerer and former president of the Cave Research Foundation.
Andrew Emond, a Montreal-based photographer, amateur geographer, and DIY gonzo spelunker of the city’s sewers and lost rivers, has just re-launched his excellent website, Under Montreal. The revamped site now comes complete with a fascinating, interactive map of the city’s subterranean streams, documenting Montreal’s invisible rivers for all to see.
NYC’s East Side Access Project continues apace, and these recent images, taken last month by MTA photographer Rehema Trimiew, show a whole new view of the mind-boggling underground caverns now being constructed beneath Manhattan. From raw walls of exposed geology to this, the space is finally taking on the look and feel of architecture.
You don’t even need a flashlight to look for cave paintings in the dark: you just need the sound of your own voice. By listening to echoes as they walk through Spanish caves, acoustic archaeologists are unlocking the secrets of underground soundscapes.
