Shocked quartz grains and melt rock clasts have been found in fluvio-glacial sediments deposited by a river that drains the area of the structure.

The results of this dataset were combined with existing data acquired by NASA as part of their Program for Arctic Regional Climate Assessment and Operation IceBridge.

Fieldwork was also carried out at the margin of the ice sheet in the summer of 2016 and evidence of an impact structure was found in sediment samples taken from the river draining the crater.

[1] Apart from the clearly-defined circular depression, the identification of the feature as an impact structure is based on field samples taken from fluvio-glacial sediments from the outwash deposits of the river that drains the crater.

[2] Uranium-Lead dating was used on both undeformed and shocked zircon grains found within the identified melt rock clasts sampled during field work in 2019.
