By estimating the timing of glacier retreat and sea - level ascent , the investigator determined that the only prison term these stone circles could have been created would have been around 11,000 yr ago , during a period of volatileclimate changeas the glaciers rapidly melt at the end of the last shabu age . This time form fits with alike gemstone roofy bump in Norway that have been date to 11,000 to 10,500 age ago and are reckon to be the clay of ahide - covered tentor hut , the team say .
