Day 38 - (9-27-12) - Redwood Forest and Crater Lake

As Mike said tonight, 'it seems like we've all gone downhill since the cruise.'  Three of us are still not feeling up to par.  We have congested coughs and from coughing so much our rib cages hurts.  Really all we feel like doing is laying down and sleeping.  We do pretty well until about noon and then we start to decline.  Hopefully by tomorrow we will all feel a bit better. 
Jim and I went to the Redwood Forests yesterday but to be honest it's incredibly hard to photograph a tree that is 304 feet tall, 21.6 feet in diameter, 68 feet around and 1500 years old, so I didn't.  This tree is known as "The Big Tree" and to be standing next to it makes you seem so small.

Yesterday after we came back from that we just took the day off.  Mike and Judy were laying low as he was really not feeling well at all.
Today we took off for Crater Lake and to me it seemed like we would never get there.  But we did and it was worth it as it was gorgeous.  I found it hard to believe that the depth of the water was 1900 feet deep.  The color is an amazing blue color and today there were tons of reflections.  Actually they sort of took away from the deep blue that I've read so much about.  What a beautiful spot to visit.

This lake was formed from The Mazama volcano

The famous Wizard Island

Hard to believe but it's a thousand feet down to the water

The water was such a deep blue.
We had lunch there (terribly expensive) spent around an hour walking around and decided to leave.  So here we are in Lakeview, Oregon for the night. 
Funny thing happened as the four of us pulled up at this Jerry's Restaurant for dinner, we noticed this trike pull up next to us.  As we got out of the car I looked over and said, "Hey I know you."  We had breakfast with them at the motel by Mt. St. Helens a few days ago.  So we invited them to join us for dinner.
Tomorrow we are driving all day heading toward Utah and Bryce.  We will make it about half the way there as it's around 800 miles.

record clarity depth (August 1994) 134 ft

average clarity depth 90-100 ft
Crater Lake is filled with rain and melted snow that fell within the caldera basin. Crater Lake is isolated from surrounding streams and rivers, thus there is no inlet or outlet to the lake. Its primary input is from annual precipitation in the region. Average annual precipitation is (66 in); average annual snowfall is (44 ft). It took approximately 250 years for the lake to fill to today's level 6,178 ft above sea level. The lake maintains its current level because the amount of rain and snowfall equals the evaporation and seepage rate. Lake level has varied only over a range of (16 ft) in the past 100 years.
Crater Lake is known to be the deepest lake in the United States and the seventh deepest in the world. A maximum lake depth of (1,996 ft) was recorded by a group of USGS representatives in 1886 using piano wire and lead weight. The maximum depth of (1,932 ft) was established in 1959 by the USGS using sonar measurement. This depth is referenced at the surface elevation of (6,176 ft). But since its primary input source is dependent upon the climate, lake level is subject to abrupt changes. Crater Lake partially fills the collapsed caldera of the ancient Mount Mazama Volcano. The caldera is a bowl-shape depression of about (4,000 ft) deep.
The record clarity of Crater Lake was measured at a depth of 41 m (134 ft) in August 1994. The lake clarity is measured with a secchi disk, a black and white disk lowered into the water with a cable. Its exceptional clarity is mainly due to its isolation from streams and rivers. There is no incoming stream to bring any organic materials, sediments, or chemicals to pollute the lake, although natural plankton in the lake and wind-borne pollen have seasonal effects on water clarity. Particulate materials and chemicals are mainly introduced into the lake through precipitation and run-off of the calderal walls. The caldera wall is composed of volcanic rocks that do not react with or dissolve easily in cold water, although warm water escaping from the caldera floor adds a small amount of dissolved solids.
