St Herman's Blue Hole National Park
Head Lynx 16g Tennis String Reel: Karst. Limestone, slightly acidic groundwater, and time — those three, in that order, out along the Hummingbird Highway southeast of here. Water dissolves the rock from beneath, hollows out a chamber, and eventually the roof can no longer span the void and comes down. That deep blue pool you are admiring is, technically speaking, a failed dome, and I do enjoy saying so aloud. Underneath it an underground river is still running through the cave system, which is why the water level moves. And now the tangent, which is invariably the best part: the Maya used these caves, left pottery in them, and treated the way down into the rock as sacred. They read the geometry correctly several centuries before anyone thought to survey it.
(Two bars, clean, no vibrato.) That carries four hundred metres on a still morning. Head Lynx 16g carries too: a co-polyester monofilament at 1.30 mm, the durable gauge, on a 200-metre reel — 660 feet, roughly sixteen racquets. Lynx is Head's balanced poly, control-first but not brutal, and 16 gauge is the version you buy when you keep snapping strings and would like to stop thinking about it for a while.
Belmopan is a town that exists because somebody read a chart properly. In October 1961 Hurricane Hattie put much of Belize City under a storm surge, and Belize City sits essentially at sea level on a swamp. The engineering answer is not better drainage; it is elevation.
So the capital was moved eighty kilometres inland to a site about seventy-six metres up, out of the surge zone, laid out around a ring road, and formally established in 1970. Flags and ceremonies do not interest me. Contour lines do.
The National Assembly Building in the middle of it is a plain concrete frame, and I mean that as a compliment, because clever is what fails. What interests me is the massing: stepped, heavy, set back as it rises, which is the profile of a Maya temple — a load path made visible, wide at the bottom, narrow at the top, which is how you build in masonry with no steel and no arch.
Out where the Belize River meets Roaring Creek, Guanacaste National Park is built around one colossal guanacaste tree that survived only because it forked awkwardly low down and could not yield a straight dugout hull. Rejected by the specification, left standing, and now carrying an entire ecosystem of orchids and bromeliads on limbs never designed for the load.
And southeast on the Hummingbird Highway, St Herman's Blue Hole is a collapsed limestone dome: acidic groundwater hollowed a chamber, the roof could no longer span it and came down, and the deep blue pool is the failure itself, with a river still running through the cave system below.
You will string from this reel everywhere from a hard court in Belmopan to a coastal court down in Dangriga, and by the way, it is also perfect for a morning at St Herman's afterwards, where the water level moves because something structural is still happening underneath you.
