Las Nieves

Las Nieves is a pretty hamlet, in the municipality of Santa Cruz, but about 2 km outside it as the crow flies. If you’re fairly fit, there’s a pretty (but rough and steep) footpath between the two. More importantly, Las Nieves has the most gorgeous church on the island. It’s also one of the oldest, dating from at least 1423 (they had missionaries here before the conquest in 1493). The…

Cochineal and Prickerly Pears

In the 1850s the export market for Palmeran wine collapsed, and somebody had the bright idea of going into cochineal production. Before the advent of synthetic dyes, this was far and away the best red dye available, particularly for wool. For one thing, it doesn’t fade. Cochineal is made from a parasitic insect (Dactylopius coccus), which lives on prickly pears (tuneras), so the plants and insects were imported from Mexico….

Prehistoric Rock Carvings

The people who lived here before the Spanish invasion in 1493 were called Benauaritas. Since they didn’t have writing, not all that much is known about them, and what there is comes from the invaders. Not exactly an unbiased source! Their technology was pretty basic, maybe because the climate in La Palma is kind enough not to encourage things like weaving. They wore skins, lived mostly in caves, herded goats…

Strange Caterpillars

Yponomenta gigas caterpillars and web. I’d never heard of caterpillars that make cobwebs before, but these do. Like many others caterpilars in the family of ermine moths, they form communal webs. I suppose it discourages birds from sticking their beaks in. My book on Canarian insects doesn’t mention them at all, but then they aren’t easy to find unless you know where to look. They live on the Canarian Willow,…

Pyroclastic Flows and Dykes

The whole island of La Palma is volcanic, but it’s extremely young. The oldest rocks are only about three million years old, so there’s no dinosaur fossils here. Much of the island is basalt – a dark grey rock which tends to form hexagonal columns, like the Giant’s Causeway or Los Organos on La Gomera. Over thousands of years it weathers to a lighter grey or brownish-grey. The red rocks…

SuperWASP, the Planet-Hunter

Superwasp open for business, Roque de Los Muchachos
April 4, 2014

Most of the telescopes at the observatory here look spectacular even from the outside. SuperWASP looks like a big garden shed. It’s the white thing at bottom left. Even when it opens up, it still doesn’t look like a professional telescope. To me, it looks more like a small missile launcher. The equipment isn’t that spectacular either. As modern telescopes go, it was built for peanuts. It has eight cameras,…
