The geology of Pembina River-Moon Lake Natural Area reflects Alberta's sedimentary rock foundation and glacial history. The bedrock consists of sedimentary formations including sandstone, shale, and coal deposits formed during ancient periods when shallow seas and swamps covered the region. The Pembina River has carved through these layers, exposing geological formations in valley walls and creating the current landscape. Glaciation during the Pleistocene epoch deposited extensive till across the region, creating rolling terrain and poor drainage that led to wetland formation. Glacial retreat left behind various landforms including moraines, outwash plains, and kettle lakes such as Moon Lake. The soils vary from sandy deposits in some areas to heavy clay in others, influencing vegetation patterns and land use. The river continues to shape the landscape through erosion and sediment deposition.

The natural area experiences a continental climate with cold winters and warm summers typical of central Alberta. Summer temperatures typically range from 15-25°C (59-77°F), with occasional warmer periods reaching 30°C (86°F). Winters are cold with temperatures often dropping below -20°C (-4°F) and substantial snowfall from November through March. Spring and fall are transitional seasons with variable temperatures and conditions that can change rapidly. The area receives most precipitation during late spring and summer, with thunderstorms possible during warm months. Chinook winds occasionally bring rapid warming during winter, creating temporary temperature increases. Visitors should be prepared for weather variability, mosquitoes and biting insects during summer, and cold conditions from fall through spring.

The Pembina River region has been utilized by Indigenous peoples for thousands of years, with Cree and other First Nations having deep historical connections to the land.
