| Geomorphic Feature | Examples at Eramosa Karst | Significance |
| Karren | A few excellent examples of a variety of small scale karren | |
| Dolostone pavement | A few limited examples | |
| Grikes | Numerous examples | |
| Collapse dolines | A few examples | |
| Suffosion dolines | Widespread in Eramosa Karst | * Provincial: although reasonably common in Ontario, this is the highest concentration known in the province. |
| Soil pipes | Widespread (typically associated with suffosion dolines and drainage courses) | * Provincial: the only known location in Ontario; potential to be the type-example for an erosion mechanism of doline formation. |
| Karst windows | Pottruff Cave Nexus Cave Window Entrance | * Regional: Pottruff Cave is the largest example along the Niagara Escarpment. |
| Caves | Nexus Cave | * Provincial: of the three caves of its type in Ontario, it is the largest, most complex and best preserved |
| Solution shaft | Unnamed shaft, Nexus Cave | * Provincial: one of only three in-cave examples |
| Sinking streams | Nexus, Stewart, Phoenix, Kinney and McGill Creeks | * Provincial: the largest concentration of sinking streams in a relatively small area. |
| Overflow sinks | Various excellent examples situated downstream from Phoenix and Stewart Creeks | * Provincial: clearly the best example in Ontario of overflow sinks in mantled karst developed in well bedded carbonates |
| Dry valley | Nexus dry valley | * Provincial: the very best example in the province |
| Blind valley | Nexus Creek blind valley (at the sinkpoint) | |
| Half-blind valley | Phoenix Creek, Stewart Creek | |
| Resurgence (spring) | Pottruff Spring, Nexus Spring | |
| Exsurgence (spring) | Unnamed spring, situated 280 m northeast of Pottruff Spring |
