Location of Podwiśniówka pit lake against A – significant geotectonic structures (Żylińska et al. 2006), namely Holy Cross Mountains (HCM), Precambrian East European Craton (EEC), Palaeozoic Caledonian and Variscan fold belt (P) and Carpathian Alpine orogenic belt (CA); B – a topographic map; C – Digital Elevation Model; D – orthophoto maps (https://earth.google.com); E – relief profile. The red dots in B–D and the boat symbol in E indicate measurements in the lake.
