The ~65 Ma old Deccan Traps cover about 0.5 million km2 in western and central India. The Deccan Traps region has huge geotourism potential with several potential geoheritage sites1–3. We report here the occurrence of spectacular columns in basalt near Bandivade village (16°49′18″N and 74°01′0″E), in Kolhapur district, Maharashtra (Figure 1).Full Text

Slot canyons, with extremely small width–depth ratios, are rare geomorphic features that develop under limited range of fluvial conditions. We report the occurrence of such an uncommon canyon, developed on the crest of the Western Ghats in the Deccan Traps. The canyon is a tourist hotspot. Geomorphic studies reveal that the Sandan slot canyon is 2–30 m wide and up to 100 m deep. Based on compelling field evidence we hypothesize that the morphology of the slot canyon is the product of the interplay between flash flood-induced excavation of a dyke and slope failures.Keywords

Sand sheets and mounds occur along the eastern bank of Hagari River in Anantapur district, Andhra Pradesh, India. These wind-blown sands are considered to be deposited by a flood about 1–2 centuries ago. Based on the description in the British era District Gazetteer, we infer that the sands were most likely deposited by a flash flood in May 1851.Keywords
