V roce 2011 se vydal badatel Brent McGregor na odv\u00e1\u017enou expedici do ledovce Sandy, kde se spustil po lan\u011b do trhliny, kter\u00e1 vedla k objeven\u00ed jeskyn\u011b Snow Dragon. Tato rozs\u00e1hl\u00e1 komora o rozm\u011brech 24 metr\u016f na \u0161\u00ed\u0159ku a 12 metr\u016f na v\u00fd\u0161ku se stala branou do labyrintu propojen\u00fdch chodeb, kter\u00e9 nakonec vytvo\u0159ily nejv\u011bt\u0161\u00ed syst\u00e9m jeskyn\u00ed v ledovci v ni\u017e\u0161\u00edch 48 st\u00e1tech.<\/p>\n\n
