“HIGHLIGHTS
• Hydrologic models were used to assess remotely sensed surface water estimates.
• The accuracy of satellite surface water estimates diminished for waterbodies < 2 ha.
• Vegetation reduces accuracy of surface water detection, especially during wet years..."

Rock on the beach at Barnum Point, Camano Island, WA. Looks like a granodiorite peppered with xenoliths. Igneous petrologists chime in. Likely weathered out of the till that caps the bluffs or a dropstone from floating ice on marine water incursion during the Everson interstade. Source rock provenance not known. Ref. Geologic map of the Juniper Beach 7.5-minute quadrangle, WDGER Geologic Map GM70. #geology #igneous #xenolith #iceage #glaciation #intrusive #PNW #washingtonstate #CamanoIsland
