My first hike of the new year was to the Lexington Reservoir near Los Gatos. Fellow USGS postdoc Kayla Iacovino (@kalyai) came along to help search for blueschist-facies rocks in what’s locally known as Franciscan Complex melange. Now, I’m getting pretty good at spotting serpentinite – not that it isn’t fairly distinctive – but I’ve been hoping to see some blueschist as well. I found this USGS publication which shows a sample of blueschist from a spot “near” Lexington Reservoir in Santa Clara county, so that was where we headed.
