Holes of the Jura

The Winter Sport for all members of the family
(except the small ones)

The Swiss Jura is made largely of karst limestone and in many places has washed out in dark holes and chimneys small, medium-sized, and frequently gigantic. There's great sport to be had in seeking them out in the snow, darting up close for a snapshot, and backpedaling frantically, giggling in triumph.

Since the Dawn of the Century, we've been stumbling all about in the forests of the Jura on snowshoes, looking for these things and trying to talk Dr Joe into plummeting down into some of them and waving cheerily back up at us for the perfect photograph. Our luck is holding so far.
