As of today, out of season, returns ~November. Earth Exhibit tracks the live conditions and flags it the moment it is on.
Naturally formed blue ice caves and hollowed ice passages appear on and within the Matanuska Glacier when winter temperatures freeze meltwater conduits and create stable englacial spaces.
These features are dynamic and ephemeral, most reliably visited under guided winter conditions when guides have scouted safe caves.
