Despite dire forecasts of the tropical storm lasting until Sunday, the weather cleared early yesterday afternoon and the resulting mist lifted by about 5pm. Hence what promised to be a wash out for the mapping group actually turned out to be a productive day with a number of panoramic photos shot, and the initial experimental photos were stitched successfully. We are finding that manual exposure and auto focus are good, productive combination. Adaire has been using her artistic talents with the whiteboard images that mark the beginning of each location's photo sequence - see the photos below for some examples.
Yesterday, the mapping group also switched the HOBO temperature sensors at the springs. At the moment, they do not appear to show evidence of a hot spring but surface runoff has been a big problem. An attempt has been made to alleviate this by attempting to divert runoff to the possible hot spring, and to locate the sensors deeper. Digging in the hotspring site found two soil types. This possible mystery was solved when we looked at Spring 3 (more of a storm washout, really). The 'top soil' is a brown soil containing a lot of fine gravel/coarse sand. Under this lies the 'bed rock' - an orange clay, probably alluvial. Dr. B and myself think that soil analysis will probably make a good project for next year.
Map Updates: The main house property line has been added to the online map. The buildings have also been added, but they need photos in their pop-up windows. The Map Group has lots of data that is being processed, and should be online today/tomorrow.
