K is due to joints and openings along bedding planes. Fracture decreases as depth increases. For granite, horizontal fracture due to removal of overburden. Gas vesicles and lava tubes contribute to the n and K. Also fracture. E.g. Basalt in Columbia plateau.
Permafrost table creates perched water in the active layer.
Water below the permafrost layer is confined and the permafrost layer is the confining layer. Therefore, no recharge. Due to warm weather rock break down by physical weathering, thus, more permeable. Bedrock aquifer do exists, recharge through adjacent mountain. Thus, recharge could be done during a wet season.
