The total excavated area makes up approximately 250 sq. m. Thanks to perfectly preserved site cultural layer, the remains of 6 dwellings and 2 middens were discovered at site. The perspectives for further surveys have been studied not only for the settlement main area, but also for its tail area, which is found in turf deposits.
