Standing on the floating dock, you look across the water at the many floating heads and brightly colored buoys. This may be a little more difficult than you had originally anticipated. Still, you've come this far and you've already paid the entrance fee, best to make the most of things and explore the kind of antics you can get up to.
You turn your attention back to the rented gear laid out in front of you and spare a glance for your buddy next to you, whose gear is nearly assembled ready for buddy checks. Bending down to complete your preparations, a blast of cold air is suddenly funneled down the entry tunnel, raising goose bumps on any exposed skin, which in reality is nearly all skin thanks to the itty-bitty blue bikini you're sporting.
Between donning swim wear and pants that morning you'd caught a glimpse of your reflection and been pleased to notice your time in the gym has been paying dividends. The cuts on your arms have become more defined, solid legs and shoulders, tight little ass and a stomach that couldn't quite manage to be called flat owing to the abs that were poking through. In short, you looked hot. And capable, a winning combination.
Ignoring the intrusive draft of February air, you turn back the task at hand, connecting hoses, checking valves and gauges until you too are ready to enter the water. You turn to your buddy and swap gear, quickly completing buddy checks and applying defog to your mask. You kneel down to give your mask a quick rinse and as you do, you inhale a cloud of rising steam, causing the whispy hairs at the back of your neck to curl free of the tightly laced French braid trailing in a dark brown rope down your spine to the center of your back.
Here at the eleventh hour, you make a snap decision. Anxious though you are to break in your brand-new pink and white rash guard, you decide now is simply not the time. You regretfully peel it off, hoping the tight turtleneck won't muss your hair and make a tight mask seal difficult, and you pad halfway up the tunnel to deposit it with the rest of your street clothes. February in the mountains it may be, but geologic forces beneath the Crater keep the water of the natural hot spring heated to an average of 94 F, at the surface. And here the normal rules of hydrodynamics are broken. The deeper you dive, the warmer the water becomes as you draw closer to its underground source.
It's chillier here in the tunnel, the artificial entrance that has been bored out of the limestone, beehive-like structure, making it possible for visitors to simply walk in, rather than being lowered down through the chimney hole that marks the natural entrance of the structure, some fifty feet above the water. The cold seeps up through your bare toes, and you move with a dancer's grace quickly back to the place where your buddy is waiting for you. Your reservation allows you access to the Crater for only an hour, and that time must include set up and tear down, time is ticking on.
With final checks complete you quickly slip into your boots and then your BCD, your buddy helps to support the weight of your cylinder while you tightly cinch down the shoulder and waist straps. All buckled in, the two of you sit side-by-side on the floating dock, don your fins and give each other the 'okay.' With enough air in your BCD to be positively buoyant and regulators in, you complete a controlled seating entry, sighing slightly in pleasure as the warm water wraps around you like a gentle caress. Together, you paddle the short distance to the square of buoys at the center of the Crater and make eye contact. You buddy flashes you a thumbs down and an okay, a question. "Are you okay to descend?" You respond with an affirmative okay of your own and it's inflator hoses up as you descend into what seems like the world's largest hot tub.
You keep one hand on the mooring line of the buoy and a close eye on your depth gauge, carefully controlling your descent. Equalizing the pressure in your ears has always been a struggle, you don't even enjoy flying for that reason, and you want no issues today. Within a few minutes you arrive at the maximum allowed depth of forty feet. This is where the hour-glass shape of the Crater narrows before opening up again at the bottom. A small squeeze of your inflator hose to become neutrally buoyant and you're ready to start exploring your underwater environment.
Directly beneath you is a horizontal square of PVC pipe, marking the limit set for recreational divers by the Crater. Off to the side, just barely visible in the gloom is a suspended wagon wheel, another depth marker just for fun. You know from experience that further up and bolted to the silt covered wall is a stationary platform, there's a light marking its location, but the platform itself is invisible. You turn to your buddy and wave a finger in a circle, indicating that you'd like to take a lap and he signals his ascent. The Crater is small and it isn't long before your exploration has hit all of the highlights; perhaps it's time for a little mischief.
Checking to make sure your buddy is watching, you twitch aside your bikini bottoms to give him a flash of bum. His answering 'ok' and wiggly eyebrows boosts your confidence and you know without having to look to closely he's grinning around his regulator, if he keeps this up his mask will spring a leak. With a self-satisfied smirk of your own, you grow bolder. Facing him fully now, you check for traffic before freeing both breasts for his watching enjoyment. The dim lighting and the silt that drifts off the Crater's walls make discerning details difficult, but even so you can tell the warmth of the water has left your nipples flushed and perky. He moves in to better investigate for himself when you suddenly find you've drifted rather close to the Crater wall. It would be a shame if an accidental brush were to disturb the silt and further degrade the visibility for everyone else in the water that day, and Crater rules ask you maintain a five-foot distance.
Your buddy's grasping fingers are frustrated when you slip your swim suit back into place, and just in time. Another dive pair has been making their descent near by. The quiet in this enclosed place is nearly absolute beyond the gurgle of your own bubbles, and you hadn't noticed them at all until they were practically on top of you. Quickly, the two of you resume swimming in laps, 'nothing to see here guys,' you think to yourself. You ascend slightly and alight on the stationary platform. This would be an ideal location for an underwater encounter, warm, fresh water, with a solid, silt free surface, the only drawback being a lack of privacy. You had to book two months out to schedule dive time on a winter weekend, and it isn't as if you could afford exclusive access, if such a thing even existed. The Crater is so popular that a group of dive enthusiasts has driven twelve hours from Montana just to complete a stress rescue certification in the dead of winter.
