A shelter and associated methodology for operating a shelter that is selectively positionable between an operable raised mode and an idle lowered mode. The shelter has an outer frame with a first upstanding perimeter wall defining an open top. An inner frame has a second upstanding perimeter wall nested within the first upstanding perimeter wall in the lowered mode. Means are provided for raising the inner frame through the outer frame's open top and above the outer frame in the raised mode. The shelter can further include a second inner frame having a third upstanding perimeter wall nested within the second upstanding perimeter wall in the lowered mode. In that case, the means for raising is further configured for raising the second inner frame through the inner frame's open top and above the inner and outer frames in the raised mode.
