| This is the process by which rainwater erodes limestone cliffs and creates limestone caves and sinkholes. |
| Springs, sinkholes, and caves are just a few examples of the types of karst features commonly found in the limestone and dolomite geology of this region. |
| Just to the west of Mount Schank, an extinct volcano created a series of deep sinkholes, which harbour some unusual life forms. |
| No longer is there a bottomless pit of dollars to salvage and subsidize sinkholes like VIA Rail. |
| Collapsed sinkholes generally have steep rock sides and may receive streams that then flow underground. |
| It also keeps an up-to-date National Karst Database recording visible sinkholes, springs, soakaways and known building damage. |
