Leduc reefs have grown to widely varying heights and aereal extents along the Rimbey-Meadowbrook trend of central Alberta, resulting in significantly different seismic signatures. Three examples considered in this paper include two high-relief or full reefs from the Leduc-Woodbend field, an atoll and a pinnacle, each around 200 m in height but differing greatly in areal extent, about 100 km² for the atoll and 1 km² for the pinnacle. The third example, a low-relief or basalt reef from the Morinville field, is about 100 m high and 1 km² in areal extent.
