Over a drought a mix of sap salts and acids accumulates and coats the bark surface to form the basics of a rough detergent. When it rains, these ingredients mix with the water and start sudsing up. The froth (foam) is from the agitation of the mixture as it runs down the rough bark during its flow to the ground. I learn something new every day. πŸ’¬πŸ’¬πŸ’¬πŸ’¬πŸ’¬πŸ’¬
