Topic (s): frozen ground or permafrost. WebOpen (hydraulic) system pingos. These occur in hydraulic systems where intra- or sub-permafrost groundwater flows under a hydraulic gradient to the pingo site and maintains a sub-pingo water lens that freezes to form a body of injection ice (hydrolaccolith) that uplifts the surface permafrost to form a conical hill (Figure P64).
