@NunavutBirder@mas.to @VATVSLPR@c.im How much of ground thaws in summer for them to burrow some dens ? Or are they able to dig into permafrost to make deeper dens that have more constant temperature year round? Or do they find areas between rocks where they can plug in gaps with dried vegetation?

@jfmezei@cosocial.ca @VATVSLPR@c.im Active layer is only a few inches deep. They den in rock crevices and bivouac in the same and snow drifts. Last week I hike up the canyon behind the cabin and there were several little caves in drifts at the base of cliffs. The area is littered with hares this year. On Ellesmere hares form large herds. And there is one place here where that happens. A few years back I counted over 200 there.
