Made another visit to the lava flow area. Activity was very subdued with many stagnant lobes of Pahoehoe lava scattered all over the flats below the pali. Finally found one small spot of more fluid breakouts. The pali flows were also sluggish. If it weren’t for the steep terrain they are on, they too could have easily been stagnant.
It was still a good visit. Windy as usual with some rain. Only took a few photos. Again, the new Nikon D800 is an amazing camera. A few from this hike will be in the Kona stores by late next week.
Added images from around here in Kona to the website. Just shots captured while playing with the D800.
Mostly I’ve been shooting stock photos.
This is a short post. Still waiting on the right weather conditions for my larger photo expeditions.
Here’s a post on lava rivers/streams. Since Pu’u O’o vent has been sending streams out from the new fissure on its east spillway, I decided it was time to explain the difference between this type of river vs the more normal lava tube breakout. People have asked a lot lately if I’ve been out there yet. I haven’t and the reason is, this type of river and its location are just too dangerous. Plus the area is very difficult to hike due to the horrible lava I explained in a earlier post. The east spillway of Pu’u O’o is very steep so, the flows move very fast up there. They also overflow their banks at anytime and any location so, getting close even if you made it that far is too risky. If the lava can move faster than you can, it’s too dangerous! Also, the lava can easily overflow suddenly from Pu’u O’o vent again and engulf this entire area like it did when this all started. Not to mention that much of this lava flows very fast and hollow leaving that nasty shelly pahoehoe or A’a lava flows that can be well over 15′ high. Stay away!!!
The samples I show in my photos here are from lava tube overflows. The main tube gets over-capacitated and a weak section of its roof is lifted away allowing the lava to escape. The section lifted away is called the “Manhole Cover”. I have witnessed this before on a large-scale. Included is a very rare photo of one that survived the overflow. 99% of the time the section is swept away by the powerful surge of lava. The higher elevations are the best for these lava tube overflows. They’re generally more powerful and much larger than on the flats. Getting caught by an event like this is one of the many occurring dangers that can kill you out there. Hiking active lava flows is an art that is learned carefully over a period of several years. Hiking a mature lava tube is one of my most favorite adventures to do. You have to know what you’re doing. Its nothing like the short walks to ocean entries.
The Manhole Cover image of course has a lava tube skylight. This was left over as the overflow was very brief and at a sudden 10′-15′ drop that allowed the lava to have an intense internal lavafall. The breakout occurred at the highest of the many small pali’s. I spent 8 hrs at this location. The following week I went on a skylight exploration hike and found 21 active ones. By far the most I’d ever seen on one hike. A week later they were all sealed up. These were 4-5 hr one way hikes. My next post will show some of my images.
