The underwater geology of Roatan was really fascinating. Where I usually dive on Whidbey Island there are not spectacular canyons with smooth round-shaped walls full of ledges and holes, caverns and narrow swim-throughs like in Roatan.
One of the dive sites that really impressed me was the
Spooky Channel. Unfortunately the photographs and video clips that I took during that dive were stored in one of the memory cards that were stolen at West Bay beach. The only visual reference of that dive is a quick sketch that I drew in my log book:
The sketch does not give justice to how the underwater topography of the site really unfolded in front of my eyes while swimming first over a shallow reef then into a canyon whose space got smaller until there was just enough room for a diver to swim through without getting stuck and reaching a deeper channel with higher vertical walls while the visibility dropped from 80 to about 20 Ft! (That's why the site is called
Spooky Channel). Instantly I felt I was in a familiar environment and I thought of home.
I tried to follow the group down to the bottom of the channel but my ears oddly and stubbornly did not want to equalize. My buddy waited for me while I tried several times to release the pressure inside my ears but it did not work. While hovering at about 30ft I saw the other divers disappearing slowly into that poor visibility. Then I signalled to my buddy to keep swimming in the same direction maintaining a depth of 30 fsw. My ears were able to cope without hurting.
Maybe it was a blessing that we did not keep up with the group at the same depth because it was like swimming in the middle of an uncanny threshold. When I looked up I could see the sun rays penetrating the blue water and pinnacle corals stretching out towards the light, when I looked down I could barely make the white sandy bottom out, the water was like fog that turned solid rock into a more ethereal material and when I looked on both sides I could gaze at the solid walls of the channel full of cracks and holes that looked totally lacking of life at first glance. Then I looked harder and banded coral shrimps began to appear, then an upside down king crab and small shy tropical fish.
After a while I spotted the bubbles of the other divers. Eventually they came into view. My buddy and I were swimming above them. They had reached the end of the channel, turned around and began to swim back. I decided to give another go at equalizing my ears. Slowly I began to drop from 30ft toward the bottom. This time my ears cooperated and we were able join the group at about 50 fsw.
We did not go through the narrow swim-through again but slowly swam upwards along the walls of the channel until we reached the shallow part of the reef. At some point along the way by magic the visibility switched from 20 ft back to 80 ft.
