If anyone's interested, we just returned from Ecuador. These were the conditions in our experience:
Rucu Pichincha - Great scramble on the SE ridge. No snow on the route. Socked in at the summit. We got rained and snowed on.
Illiniza Norte - Snow starts a few hundred feet below Nuevos Horizontes. Sidehilling on steep, unconsolidated snow at Paso de la Muerte. Socked in at the summit. Weather was rain, snow, sleet, graupel.
Cotopaxi - Good hard snow from the refugio to the glacier. Good bootpack on the glacier. Interesting route with some fun crevasse threading and a little bit of ice. Turned around at 18900' due to frostbite concerns for one of my team. The ice ramp looked easy and other groups were just using quick belays. Perfect weather.
Chimborazo - Via El Castillo. Strenuous but boring. No crevasses on the route. Steep and often unconsolidated snow for 4000'. Incredible views from the Whymper summit. Snowing up to El Castillo, great weather above that. Little rocks were pelting us on the descent from El Castillo.
