Why is the sap blue?
Thanks for the comment Jon – I think it’s mostly an artifact of the forest lighting and suboptimal choice of white balance. The sap usually looks more or less white to me. It starts out clear, but over time fogs up and ends up hard and opaque like you can see in the more close up photo. http://www.sitkanature.org/wordpress/wp-admin/edit-comments.php#comments-form
