Abstract: The known languages of the Americas comprise nearly half of the world's language families and a wide range of structural types, a level of diversity that required considerable time to develop. This paper proposes a model of settlement and expansion designed to integrate current linguistic analysis with other...
My two minor obsessions captured at the same moment. Here are pictures of my favourite bicycle, an old school build using a custom #DaveYates frame, resting against my favourite rock, a beautifully smooth #glacial erratic composed of a very hard, fine grained, mid grey #igneous rock with pale mm-cm sized plagioclase phenocrysts. Generations of bottoms have enhanced the glacial smoothing 🙂. Located in #MaxwellPark#Glasgow#geology#cycling
USGS: Volcanoes "On Aug 15, a small glacial outburst transitioned to a debris flow in @MountRainierNPS
. Flow remained in remote upper reaches of Tahoma Creek drainage (no damage). Event detected by #USGS lahar monitoring stations, like TABR. Strongest signal occurs as flow front passes." #glacial#outburst#melting#MountRanier#debrisflow
