Luxury Hotels In Key Largo

Understand the Ground Beneath the Upper Keys

Key Largo Limestone formed from a coral reef during a warmer interglacial period in the Pleistocene, when sea level was higher. The formation is exposed along the Upper Florida Keys. It gives the islands a history connected with marine growth long before the present shoreline took shape.

For a traveller interested in landscapes, that origin changes the way the place is understood. The rock itself is part of the marine story. Consider the distinction between a living reef and the geological evidence left when a former reef became limestone.

Read the Fossils Within the Rock

The limestone is white to light grey, with coral heads embedded in sand-sized grains of calcite. Star and brain corals are among the forms represented. Fossil molluscs, echinoids and bryozoans record other marine organisms alongside the coral framework.

This material gives a natural-history interest detail beyond the general phrase ancient reef. Look at the relationship between a larger coral form and the smaller grains around it when studying an example. It records a community of organisms and the material that accumulated among them, rather than one solid mass produced by a single animal.

Give Geological History a Place in the Stay

Playa Largo Resort & Spa provides one accommodation reference in Key Largo. Alongside the hotel setting, the geological subject can appeal to someone who enjoys understanding how a landscape was made. It brings a longer timescale to a place often approached through its immediate coastal appearance.

The Duck Key destination guide offers another Keys reference for a wider journey. Compare settings for their individual character, with Key Largo's fossil-reef history giving this chapter a subject of its own.
