The sun and clouds make for an interesting contrast on the south shore of Mývatn. The name Mývatn means "Midge Water" or "Midge Lake". Midges are tiny flies that can swarm on warm summer days. They rarely bite, but fly into your nose, eyes, ears and mouth - making outdoor activities utterly intolerable unless you wear a headnet (which works quite well). Luckily, the wind often keeps them away.
