What are some features that might allow you to identify upwarped mountains?

The upwarped mountains are formed due to volcanic eruptions. The release of hot magma from the earth crust results in the uplifting of earth crust. The uplifted earth crust will form a dome shape. The water bodies like river may flow through these mountains and water erosion create ridges in the softer  upper mountain soil. Dome shape and ridges due to water erosion are some features to identify upwarped mountains.
