Castle and Heart Lake Hike

One of the best outdoor writers in America (IMHO) is Soul-soaring views await from perch above Heart Lake. In it he beautifully described

Heading up to the Shasta Area we found our first glimpse of the 14,179-foot (4321.8 m) Mount Shasta from the dog area at a rest stop on Highway 5 just south of Castle Crags State Park.

As we got closer we kept getting glances of the always larger mountain peaking through trees or just around corners.

We arrived in the area on a Monday so as to minimize weekend crowds and traffic. We could tell that Castle Lake was a main draw in the area with all the Castle-named items in the area. We found a nice little campsite in the National Forest right off of Castle Lake Road, close to Castle Lake Creek about half way between Castle Lake and Lake Siskiyou.

The Big Picture Of Where We Were At

On Tuesday morning we got up early and hustled the 3 miles or so to the parking area at the lake just past the Castle Lake Campground. Only one other vehicle was there when we arrived at 7:30 in the morning so we had our choice of parking spots. Not knowing how long we were going to be hiking I made Willow wear her Ruffwear Palisades pack so she could carry her own water. She uses that pack in the Medium size and the saddle bags perfectly fit a 1 liter Platypus SoftBottle in each side. As it so happened she ended up carrying that water for me as she had ample opportunity to drink water straight from the lakes and streams we were playing around that day and water from the source always tastes better than bottled water.

She Wasted No Time Getting Her Feet Wet

We went through several different packs before settling on this one and during that time I quickly learned to not put items that would be damaged by water in it so now I don’t fret when she starts swimming or professional-grade wading with it on.

Castle Lake is a typical glacial “cirque” lake that was formed about 10,000 years ago during the Pleistocene Era when much of this area was covered in glaciers. The high wall at the western end of the lake is called the Cirque Face and are the remains from where the glacier did most of its erosive work. As the glacier receded towards the north end of the lake it left behind tons of debris called the terminal moraine which blocked off the area and allowed the lake to form.

The lake at the cirque face is up to 120 feet deep while the depth at the moraine and outlet is only about 10-15 feet deep. Castle lake is one of the longest scientifically observed lakes in the world with studies started in 1938 and still ongoing today. There are still a few cabins on the northeast side of the lake housing researchers and equipment from the University of California, Davis. In aquatic ecology circles Castle Lake is one of the most famous lakes in the world! Limnological studies started in 1959 focused on the growth of algae (or lack thereof) in the lake. Researchers soon realized that the dominant mineral type in the Lake Castle watershed is granite which is lacking in essential plant nutrients such as Nitrogen and Phosphorus. This explains why Castle Lake has relatively low algae growth which allows its waters to be some of the clearest in the world, on par with Lake Tahoe.

We took an hour and walked around the lake in a counter clockwise direction, past the research camp until we could not go any farther easily. Heading back towards the parking area we kept going around the eastern side of the lake until we saw the sign pointing towards Little Castle Lake and decided, why not.

With the path unclear and signs pointing the way non-existent we just headed in the relative direction and hoped for the best. Probably half of the two hours it took for us to find our way down to Little Castle Lake was spent stumbling around cross-country and breaking trail. We experienced the whole gamut of “trail” types from flat and smooth to steep and rocky with a some tripping underbrush and face-smacking tree limbs thrown in for good measure. It was hard work but we made it.

I removed Willow’s pack to give her a quick break as we both had a drink and a snack in the little campsite we found near the lake.

Our short rest over we got her pack back on which was now several ounces lighter, took a look at our Garmin eTrex to get an idea which way Heart Lake was and started in that direction. About 45 minutes later we crested the lip of the little cirque that held Heart Lake. Upon seeing the lake Willow rushed down towards the lake and only stopped from plunging head first into it when I issued the “Stop” command and quickly took this picture.

Once the photo was taken I released her and she finished her mad dash into the lake.

Sweet Relief

She certainly didn’t need to go and cool off in the lake as by now it was only 10:45 in the morning, it was not a hot day and the hike up to the lake had been of only moderate difficulty. But, she’s my girl and I allow her these types of enthusiasms. Once she finished with her soak I coaxed her back out and up onto a downed tree for a few beauty shots.

Taking the advice of Mr. Stienstra we headed around the right side of the lake so that we could get to the back side and hopefully get an iconic photo across Heart Lake with Mt. Shasta in the background along with the slight infinity pool feel of the situation. While it was a partly cloudy day and a bit of a breeze prevented the reflection of Mt. Shasta in the lake I still think we succeeded pretty well.

Why would I be almost sitting in the water you ask? Well, just as we had made our way around to the back side of the lake some other people showed up and sat down right in the way of our photo.

Move Please

They immediately realized that fact and shouted apologies and I joked that I could just Photoshop them out later. While on the one hand I cannot afford Photoshop and on the other I have become an enthusiastic proponent of FOSS programs. With those criteria I have become pretty well versed in using GIMP for all my photo manipulation needs. But instead we just crouched down and used the crest of Willow’s big, black head to blot them out. Easy peasy.

Walking away from Heart Lake we were able to look back down upon Castle Lake.

And just for good measure, a panorama from the same spot:

By now it was 1:45 in the afternoon and so we began our descent back down to Castle Lake and the Tacoma. We said “hi” to a couple small groups of people heading up to Heart Lake and answered their questions which consisted solely of “how much farther?” By the time we made it back down we were both feeling spent but thrilled at the beauty we had seen and all the scents she had smelled.

In the days after our hike around Castle Lake and up to Heart Lake we used our nice little campsite as a cool and quiet base of operations to hike around, wade in the creek and explore our little section of the forest. A 5 minute hike away from the site was a spot in the creek with several pools which were the perfect size for a cool dip.

Too Cold For Me But Willow Loved It

This was a good spot and so we took this opportunity and used our tried and true MSR Water Filter to refill some of our water storage containers including the two platypus bottles Willow had carried during the beautiful hike.

I am sitting near the base of another grand mountain (Mt. Hood) as I am writing this post literally 2 years to the day since we went on that adventure. Looking back through all the pictures really brought back the fun we had and the belief that the Shasta-Trinity area has some stunning hikes, history and geology to explore and enjoy. Now that I think about it I believe we should head that way and revisit the area on our way back down from Oregon into California. Maybe this time I can get some pictures of breeze-free water filled with the reflection of Mt. Shasta with no people in the shot. Something to aspire to anyway.

What’s the latest epic hike you went on with your furry friend?
