Beautiful pictures!! It must be something else knowing that you guys are the first people to ever see these formations. Seeing that this system does have a waterfall, how real of a threat would flash flooding of the dry cave be? I guess the presence of stalactites and stalagmites would say that a change in water level isn't common? Keep up the great work! Please be careful climbing those waterfalls as I'm sure having to swim to your exit will amplify any injury.
