Holoholo Mauna Kea - and Thanksgiving

Long and winding road -- these are KOA trees with light bark

For Thanksgiving, this week we took a lovely drive (holoholo) up the slopes of Mauna Loa. Its mass (from seafloor to top) makes it the largest mountain in the world! The drive is long and winding, but offers an amazing views and a variety of vegetation because of the wide variety of elevations..

The Big Island averages only 85 miles across, but elevation from 0 to 13,800 the results in diverse and dynamic landscape. Hawaii Island has 10 of the 14 world's climate zones offering an outstanding variety of vegetation.

Leaving the highway turnoff that's just a few miles form our house, we ventured up to a wonderful outlook at about 6500 feet where we could look down on Kilauea crater and Volcano Village. And, we could estimate the approximate location of our house. (which would be over at the far-far left)

The year 2018 was full of mother nature's surprises -- East Rift Zone eruption of course, Hurrican Hector, and a huge fire on the slopes of Mauna Loa that destroyed about 2000 acres including large number  of koa and ohia trees and native plants.




"Poop" berries
While we remembered to take the camera and the binoculars, we forgot our plant identification books, but were able to identify several after returning.

One plant in particular was a special find because we found it in our yard after clearing huge pile of plant debris. It is called Kukakenene -- an interesting word. kukake (the gift) KOO-KA-KAY-NAY-NAY

Nene are the official state bird of Hawaii.  Here is a watercolor painting Phil did, with a drop-in photoshop border Lunel added.

Nenes are a beautiful goose that leave "droppings" that look just like the shiny, black berries from this low growing shrub that thrives in this higher elevation.

Nene are closely related to the Canadian goose.. Some scientists believe that the Nene may have evolved from Canada geese that took a wrong turn during migration about half a million years ago. 

Right now, we have purple Iris named "Mauna Loa" in our yard but will also be hoping to find an amazing hybrid called "Mauna Loa Fire" to add to our collection.

WE ARE SO THANKFUL FOR
SO MANY BLESSINGS.

Lava "Burps" and Archaeology

Our first view --- long overgrown driveway
For the last couple of weeks I have been working (in between other projects) on a lava feature that materialized only last fall, when we had a bobcat operator clear back wide spaces on each side of our long driveway that were thick with invasive species, brittle junk trees, and mats of various vines and small shrubs. 
Me - poser/dozer for my Birthday!

(Here's a photo we took in 2012 when the front ½ acre was totally overgrown.)

As the bobcat work cleared the debris, we discovered we had a large, tall, intact flow of pahoehoe that at one time had flowed diagonally across the property.

Carefully cleaning dirt out of the cracks
Since the initial clearing took place a few months ago, this “high ground” has tempted me to uncover its secret face. For a solid week my first task was removing small bushes, debris and vines… down to dirt.  As I removed buckets and buckets of dirt, I began to see the ‘face’ of the pahoehoe that had flowed across the driveway – long before there was one. 

It was clear to me that using the pick ax would damage the beautiful unbroken lava flow, so I had to switch tools!  I got out a small triangle hand trowel and stiff brush and began the “lava archaeology” that eventually revealed beautiful swirls, folds and features all across the width of this 5 x 20’ outcropping.  As I patiently cleaned and brushed away the dirt it seemed very personal -- like a wrinkled face; the more I looked the more I saw.  (to SEE more - click on each photo)



Our house is way in the back
Heavy black shows 1955 "burps" and flows
Because this feature is 10-12 feet higher than the rest of the property, I began to wonder when this outcropping happened.  I found a USGS map that features more recent lava flows along Kilauea’s East Rift Zone in the Puna District on the Big Island of Hawaii.  There were some very late outbreaks (burps) that happened  as recently 1955.  We doubt our outcropping is that old, but it is still a reminder of how very young this island really is.
