Attawapiskat is located on the west coast of James Bay within the southeastern part of the Hudson Bay Lowland.The overburden strata in Attawapiskat generally comprise Pleistocene glacial till，post glacial lake sediments and Holocene marine deposits with more recent alluvial sediments and peat at the surface. Two Pleistocene till sheets，separated by proglacial sediments，were identified in the Hudson Bay Lowland with the proglacial sediments being absent between Attawapiskat River and Severn River[1]（角标）.The glacial tilloverlies the Attawapiskat formation of Silurian siltstone bedrock.As the last Wisconsin glacier retreated，postglacial lakes were formed in the southeastern and northwestern parts of the Hudson Lowland(including the southern part of James Bay Lowland)with stratified silt and sand deposited over the upper till.

Attawapiskat位于西海岸的詹姆斯湾东南部内的哈德逊湾Lowland.覆地层中Attawapiskat一般包括更新世冰期到后冰期和全新世湖泊沉积物海洋存款最近冲积沉积物和泥炭在表面。两个更新世至介绍，分离proglacial沉积物，被确定在哈德逊湾低地与缺席proglacial沉积物之间Attawapiskat河和Severn河[ 1 ] （角标） 。冰川tilloverlies的Attawapiskat志留系粉砂岩形成的基石。
