This submerged limestone reef system rises from the seafloor and features an intricate network of swim-throughs, caverns, and overhangs that scatter sunlight into shimmering crystal-like patterns—hence the name. The reef ranges from 8 to 18 metres deep, offering snorkelers a dramatic underwater seascape of ledges and sandy gullies to explore. Surrounded by the clear, temperate waters of a marine park, it's a favourite for spotting large reef fish, western rock lobsters, and colourful soft corals.","intermediate",null,"published",{"name":59,"amplitude":75,"phase":91,"latitude":22,"model":107,"epoch":108},[60,61,62,63,64,65,66,67,68,69,70,71,72,73,74],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[76,77,78,79,80,81,82,83,84,85,86,87,88,89,90],0.004417803242867411,0.008964836514921377,0.1677679508325492,0.013122791421924941,0.05105762341051727,0.004377548899517268,0.004654597066728796,0.004194442853500814,0.012957916039954716,0.12239248238978975,0.05140374601659953,0.02382750373733279,0.010482483358027945,0.04037739289407126,0.002797104996324778,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],46.15162470130676,223.07794878950995,181.87605579481902,41.73489003592646,58.59156107439507,126.9758859928773,33.73381084331669,225.08066086511786,108.29879275174461,175.72733080274668,172.2905017523019,172.6184418449152,330.8347573770198,64.19212332681894,235.30216438875163,"EOT20","1992-01-01T00:00:00Z",[110,116,120,123],{"name":111,"description":112,"severity":113,"season_start":114,"season_end":115},"Swell exposure","Crystal Palace sits in open water southwest of Dyer Island and can be affected by large swells, especially in winter months, creating surge through swim-throughs and reducing visibility.","warning",5,9,{"name":117,"description":118,"severity":119,"season_start":56,"season_end":56},"Boat traffic","The site is accessed by boat and lies in a transit corridor near Rottnest Island.
