July 1st, 2014 – Lassen Volcanic National Park (Day 1), CA

We are finally back on-line to be able to send some blogs (there are no signals in the area around Lassen).

Lassen Volcanic National Park is in northeastern California.  The dominant feature of the park is Lassen Peak, the largest plug dome volcano in the world and the southern-most volcano in the Cascade Range.   The area surrounding Lassen Peak is still active with boiling mud pots, stinking fumaroles and churning hot springs (more about that tomorrow).  Lassen Volcanic National Park is one of the few areas in the world where all four types of volcano can be found (plug dome, shield, cinder code and strato).

Volcano lesson (skip to the next paragraph if you are not interested) —-  A plug dome volcano is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano.   The characteristic dome shape is attributed to high viscosity that prevents the lava from flowing very far.  A shield volcano is a type of volcano usually built almost entirely of fluid lava flows.  They are named for their large size and low profile, resembling a warrior’s shield lying on the ground.   A cinder cone volcano is a steep conical hill of volcanic debris that accumulates around and downwind from a volcanic vent.  A stratovolcano (or composite volcano) is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice and volcanic ash.   The lava that flows from stratovolcanoes typically cools and hardens before spreading far due to high viscosity.   They are among the most common types of volcanoes and are known for their explosive eruptions — a famous stratovolcano is Vesuvius which destroyed Pompeii in 79 AD.

We have this much to say about northern California.  Someone needs to explain what “northern” means to it.  We had no idea that it was so hot here.  It was over 100 degrees today.  Since it was our first day here, we drove around and got our bearings and took a bunch of pictures.  We did take one hike to Kings River Falls (next to the last picture).  The first and fourth pictures show Lassen Peak.  We also found some snow that was taller than our car (which by the way is very cute and we are enjoying renting for a month).  The 8th picture shows a boiling mud pot that was right by the side of the road.   It was pretty fascinating to watch.

    The last picture is beautiful.  Not that they all aren’t. but I really like that one!

    It’s been hot here too.  I think 102 was the highest so far this week.  But then, it’s supposed to be hot here, not like northern CA.  It rained Thursday!!!  We had about half an inch.  We’re still hoping for more yet today.

    Have a ball and keep the travelogue coming!   And, I thought the description of the the various types of volcanoes was very interesting.

    Over a hundred degrees and snow taller than your car – both in one blog? Wow! We had a GORGEOUS July 4th yesterday and also today weather wise. It is now 4:15 pm and the temp on the front porch is 81. Good thing too…. our air went out last evening. I suppose it will be Monday before we can get it repaired. We had headed out the door to see fireworks when Don discovered the ‘pipe’ dripping over the kitchen window. The pan in the attic was full of water 😦 Good thing this didn’t happen while we were at the Outer Banks recently. God is good – the temp is really nice and dry – I have the windows up and a nice breeze is flowing through. With the fans on we are comfortable.
