Hranice abyss.


In 2016, we made another test measurement opposite the Hranice abyss over the valley. It was measured along the way and we found a very deep crack in the shape of a wide “V”. The new Spirio program in 2020 provided an interesting picture.

Here's another display in a different, simpler color scaleAt the time, we had no idea that there could be a cavity at a depth of 560 m. It seems that the strata here are at similar depths as about 500 m across the valley at the Hranická abyss. Perhaps we will return here and take measurements to a greater depth
