A karst sinkhole in Salaspils on the former Zeltiņi railway track (narrow gauge railway), appeared in the spring of 2021, and initially its depth reached approximately 8 meters. The visible hole above the ground had a diameter of about one meter, but by now it has already quadrupled in size. Geologists have informed us that, after studying and analyzing the local geological structure in this area, the conclusion is that it is unlikely that the current sinkhole will develop further than 10 meters in the next 10-15 years.
