One of my all time favourite dive sites in the world is “Yap Caverns” in Yap, Micronesia. This site is located on the far southern tip of the main islands of Yap and is a series of ravines and gullies cut into the reef structure with many open caverns creating a maze like dive. The best way to dive this site is to jump in the shallows and follow the twisting caverns before emerging onto a steep wall with crystal blue water. The caverns themselves are in constant flux as they undergo a series of changes over a 3 to 4 year cycle with periods of bare rock showing at the bottom interchanged with periods of bright white sand filling the channels. Photographically, the periods of bright white sand is superior to the rocky periods for obvious reasons. I took this photo during a period of time when the bright white sand had settled back in to the caverns after several years of nothing but rocky bottom. To create this photo the conditions had to be perfect with the sun shining brightly overhead but still early enough in the morning that it was not overpowering. The key was to position myself so that the rock wall blocked the main portion of the sun in order to allow the sharp sunrays to filter through the water column. The other key ingredient to make this photo stand out was the fact that a bit of swell was running which stirred up the sand and created a “sand filter” that allowed the sunrays to shine through.
