Flying south
Loop around Loop Road

There’s always lots to see …

On a flight over Big Cypress Nat’l Preserve.

We flew clockwise around Loop Road

On this trip south of Tamiami Trail, we see a swamp mirror (reflecting the clouds), the Pinecrest Chain of Hammocks, Gum Slough, Loop Road, Sweetwater Strand and Gator Hook Strand and Trail.

Steaming swamp
Think hot asphalt after a cool rain

From the distance it looked like smoke …

Or maybe dust kicked up from the limerock road.

It looked primordial, but it was actually super chilled

Only upon closer inspection did we see it was steam.

The source?

Similar to a hot asphalt road steaming after getting cooled down by an afternoon shower, the wisps of water vapor hovering over the cypress stand were the result of an ice-cold drenching from a super thunder cell.

The super cell, looking north, about 15 mile east of the strand

As good fortune would have it, I actually took a photo of the thunderstorm about an hour before and 15 miles upwind from the steaming strand. The air among the wisps was incredibly cooled and the fragrance from the cypress intense. Landing and walking in the water was further proof.

The water was chilled as if it had hailed.

Origin of domes
And how geology controls the show

What came first:

The depression or the dome?

Answer: Cypress domes form in shallow surficial depressions in the swamp’s underlying caprock, but that doesn’t explain why some depressions capped by a cypress dome and others, right next door, form a tree-free herbaceous marsh.

It might have something to do with the thickness of the marl.

Cypress dome and circular marsh

Or maybe fire frequency or flooding depth also factors in.

Mark it down as another mystery of the swamp.

Twin structures

The three new bridges into Everglades Park …

Are now fed by twin structures.

Last time saw it, it was still under construction

Next step is raising the rest of the road.

Revealing water

Water both covers …

And reveals the landscape.

The pine islands really pop out

That’s especially the case with a winter high stand of water where the needle-free cypress make the copious cover of water easier to see.
