today is my last day in hawaii :( i leave this afternoon to head back to austin, where i arrive tomorrow! long travel day/night. it's been a productive trip... and a lot of fun too!
monday was a holiday, so some of the astronomers here took me on an adventure hiking thru some remote lava tubes! we walked about 2 miles across lava fields, found a tiny hidden entrance to the caves, and then hiked in for about a mile... it's hard to judge distance underground, so who knows how far we went!
most of the lava inside the caves had a sparkly, silver tone, but sometimes there were flows of bright orange or red! cool stuff!
many parts of the cave were split into 2 levels. here you can see a huge fallen chunk of lava! that sort of sight kept me constantly looking for big cracks or potential lava flows from the end of the cave!!
there were a couple rooms in the cave with ceilings covered by these crazy lava stalactite things! they didnt hang straight down either, but rather at distinct, yet uniform angles!
