Graži vieta, Panevėžio apskritis
Klevų duobė is a karst sinkhole (doline) in the Karajimiškis landscape reserve of Biržai Regional Park, formed where gypsum and dolomite layers close to the surface have dissolved and collapsed. It lies just west of the better-known Karvės ola (Cow's Cave), on the opposite side of the road, and is reached via a field road branching off the Kauniai-Karajimiškis road. The Karajimiškis area has one of the highest concentrations of karst depressions in Lithuania, with more than 200 per square kilometer. The sinkhole takes its name from the maple trees growing around it, which are said to make it most visible in early spring or late autumn once the leaves have thinned or fallen.
