The New Great Blue Hole, or Alice Underwater

All I thought as we slowly descended was how lucky we were. The new great blue hole was recently discovered, and there was a high level of confidence that it came from an ancient asteroid strike. At the depth where all colors besides blue are absent, we saw a shimmering white oval. “Bubbles” my partner signaled. We swam down to find the source, and the second they touched us everything turned upside down. I landed on something hard, and my mask was knocked from my face. I panicked, blind at one hundred meters deep, except I was on dry land.
