Travel Log: Lava Beds National Monument

I told y'all I never take myself too seriously. ;)

I realized that although i shared the disturbing infection that's killing bats all over the states, White-Nose Syndrome, that I forgot to tell the tale of our actual trip to the lava beds.

The Lava Beds is a pretty darn cool place, and a location that has been a must on the 'the cousins are visiting and need something to do' docket since I was a little kid. Needless to say, I got a bit burnt out on the whole thing and this was actually my first trip back in over SEVEN years! Wow. (I still can't believe i've been alive long enough to have 7 years ago put me over 7 years old. sheesh.) The lava beds in Tulelake are composted of fields of chunky lava, cinder cones, and cool as all get out lava tubes formed from cooling lava flowing above and below other cooling lava. You can get a lot more information from reading their literature.

My favorite lava tube has always been the Catacombs. It's the longest one, and you can really get lost in there and shimmy down tiny crannies if you're adventurous. It is advised to bring some maps with you if you plan on shimmying... I usually just go to crawling point and turn back. i was super excited to find a little hole in the wall that was my favorite go-to place as a child. I can remember bringing one set of cousins there one summer, and the 3 of us fitting through the little hole into a whole new (secret) chamber. The following summer and another set of cousins: i was too big. :( Darned those hips! I was excited to find it though, despite my non-fitting adult girth.

The lava beds is also a great place to hike and bike. The 'cave loop' is a nice little circuit with some hills and great views. If you're going caving, don't forget to bring good lights and a sweatshirt. It's always cool down in the caves, even when it's blistering hot up on the pavement/cinder fields. Headlamps work great for clambering about, but they're not quite bright enough, so another flashlight might be helpful. The Tulelake lava beds are in California, and the cost to get in is $10 a car and is good for 7 days. There is a campground up in Medicine Lake that is just fantastic (with great fishing!) and the visitor's center is worth checking out.

It's not too often that you get to wander about in such a wild place. Lavacicles and other neat formations really show how the tubes were made, and it's easy to imagine you're being sucked down a molten hot flow of lava.

White-nose Syndrome: a Bat Epidemic!

My husband and I love the outdoors, wildlife and conservation. We can both often be heard calling out "ooh, look at that" regarding some interesting bird, tiny bug or leaping mammal. It's one of the best things we have in common and what brought us from best friends to life partners years ago. Because of this desire to keep the pristine pristine, we were not bothered at all when a nice ranger at the Lava Beds asked us to stop and answer a few questions before we went caving. Apparently there is a terrible epidemic sweeping across the country, from east to west, killing bats as it goes: White-nose Syndrome.

As you probably know, bats migrate and like to hang out in caves. In Austin, we had a large population of Mexican Freetail bats that would come north in the Winter to be pregnant and give birth sometime in the Summer.  There are bats all over North America, hibernating before heading back south, and they're catching a nasty flu. White-nose syndrome (WNS) is named for a white fungus found on the muzzles and wings of affected bats. It was first documented in New York during the winter of 2006-07. WNS has spent the past few years rapidly spreading throughout the east and north into Canada. The damaging fungus (Geomyces destructans) thrives in cold and humid conditions: can we say caves? The nasty fungus is transmitted from bat to bat, but it is very likely that some of the spores are coming from human beings and their gear when they move from cave to cave.

WNS is a pretty nasty ailment and kills over 90% of its victims. The most common bat in the US is being threatened with extinction due to this disease. Because the syndrome often affects the bats while they're hibernating, it packs a powerful punch. Bats need to sleep and conserve their energy. When it's too cold for bugs, it's too cold for the bats to hunt enough to feed themselves: bats use a lot of energy to fly around looking for food and need a lot of bugs at a time. When their hibernation is disturbed, their bodies warm up and they burn the fat reserves crucial for their survival in the winter. The growing fungus irritates the bats' breathing and causes them to wake up, often leaving their caves. The skinny, cold bats then die. As the fungus progresses to the wings, the bats are no longer able to fly, and thus starve. To this date, WNS has been confirmed as far west as Missouri and Oklahoma. Signs of WNS include:

• White fungus around the nose, wings, ears or tail
• Bats seen flying outside during the day and in temps at or below freezing
• Bats clustered around the entrance of a cave/ hibernating area
• Dead or dying bats on the ground or on buildings, trees, etc

WNS does not appear to pose any risk to human health, but bats are pretty darned important to our environment (pollination, mosquito control, etc) so I'd say that we are at risk. State and federal agencies are trying to gain understanding on the cause of WNS so that they can manage it and control its spread. The lava beds has always restricted use to caves when bats are hibernating and pregnant, but it is even more important now to avoid contact with colonies of bats, especially if you have been caving in another location and could possible introduce infection to the local bat colony.

I know i have several readers in the affected area of WNS and many more west of its spread. I hope that this article has informed you of this potentially devastating effects of this nasty fungus and that you will reconsider caving in areas occupied by bats. If you do enjoy caving, please be sure that you thoroughly sanitize all your gear and clothing before moving to another cave. The health of north American bats is essential to natural control of disease spreading (and itchy!) mosquitos and other insects. Consider providing bat houses for your local bats and please leave a cave immediately and quietly if you see bats inside, and contact a local ranger or animal control professional if you notice any signs of disease.

More information about WNS can be found at the Fish and Wildlife website. You can also report unusual bat behavior at that same website.  Sometimes observing little critters is fun and entertaining, and sometimes that observation is crucial to the survival of an entire species. If you love nature and animals as my husband and I do, please take precautions not to spread WNS and report any signs of bat disease immediately. Thanks!
