Autumn Equinox September 22, 2016

The term equinox is used by meteorologists to mark the change in seasons in spring and autumn, and occurs when the sun passes directly over the equator, creating a day and night that are the same in length.  The equinox occurs because of the tilt of the Earth in relation to the sun.  The Earth’s tilt is 23.5 degrees relative to the plane of its orbit and means that, although one revolution of the planet takes 24 hours – it’s different depending on the time of year. On the autumnal equinox, the Earth hits the turning point in its orbit where neither the North or the South poles are tilted towards the sun. That means the amount of daylight and night time is the same at all points on the Earth’s surface.

The Cove Palisades State Park is renumbering campsites in the Deschutes Campground.  This affects Loops A and B. C loop will stay the same.  Ultimately this will reduce confusion and make finding your site a lot easier.

Deschutes River Campground is open mid-May through mid-September. Please note when making reservations that if you have a favorite site, it will have a new number. You can find a map of the campground at:  http://oregonstateparks.reserveamerica.com/camping/cove-palisades-state-park/r/campgroundDetails.do?contractCode=OR&parkId=402446

 

Planning Your Fall Weekend

dsc_0023

Labor Day has come and gone.  The rabbitbrush is starting to fade.  Geese are beginning to fly south, taking summer along with them.  Crisp nights and cool mornings are a sure sign that fall is here.  Is there anything to do at The Cove once the summer season is over?  Most definitely!  In fact, fall can be one of the most magical times here at the park.  The cooler weather makes for a great time to hike the Tam-a-lau Trail.

You can access the trail from the Upper Deschutes Day Use Area and embark on a seven mile journey.  The initial climb, an elevation gain of 600 feet in the first mile, is worth it when you reach the top and see the spectacular views of the park this trail affords.  You are certain to see some of the most awe inspiring views of Lake Billy Chinook .  It’s definitely worth lugging a camera and water with you!

Not a hiker?  Being on the water provides a whole new perspective of the park, and the peace and quiet of this slower time of the year can really give you the opportunity to relax and appreciate the beauty that surrounds you.  Bring a kayak, canoe or stand up paddle board and try paddling along the Deschutes or Crooked Rivers?  Our all new non-motorized, water trail along the Crooked River will guide you on the best route for how far you want to go.

Prefer a little more information as you paddle along?  Book a guided kayak tour of the Deschutes arm of the lake!  Your guide will point out some of the geological features of The Cove and help look for wildlife as you go along.  These tours are available Thursday and Saturday mornings in September and Saturday mornings in October.  Call the park office for details and to reserve your space (541) 546-3412.

If you’d rather just to sit back, relax, and enjoy the beauty of the area;  reserve a site at the Crooked River Campground, grab some extra blankets and wood, and enjoy the colors of fall as you watch the sun set over Mount Jefferson.  If you’re up for a short walk, you can take the Crooked River Wetlands Nature Trail, accessed from the boat and trailer parking area, which provides views of the first two ponds in our wetlands.  As you walk this easy quarter mile loop, you can see the bluebird house and bat boxes built by Culver students, as well as the Certified Monarch Way Station the middle schoolers planted last school year.  You never know what kind of wildlife you might encounter along the way.

As summer leaves, the busyness settles down, and fall colors peek out around the park, so does the wildlife.  This is a great time of year to see some of The Cove’s residents who prefer a bit less human interaction.  Deer are more active as they prepare to rut, ducks are pairing up and coyotes have been howling.   In fact, just about any trail or dock you wander along could afford you that opportunity.  Maybe take a stroll along the water and see if the river otters are out playing.  Or just find a nice, quiet, pretty spot to sit and relax and see what wanders along.

DSC_0063.JPGDon’t think that just because summer is over there’s nothing to do or see here at The Cove.  Come on out and take a look.  You just might surprise yourself.

Ant Lions

An Ant Lion is not some strange Sci-Fi creature or the newest Marvel character but a super beneficial bug that naturally controls ants.

Ant Lions, also known as doodle bugs in the US because they make markings like a distracted artist, are a group of insects in the Order Neuroptera – translated as “nerve wings.”  They are part of the Family Myrmeleontidae,  which is of Greek origin myrmex (ant) and leon (lion)You know you have Ant Lions when you see these upside down cones in the dirt or sand.  These are actually traps that the (predatory) larvae set so that they can eat the ants, and other bugs or spiders, when they fall in.

The larva looks like something you would see in Star Trek The Wrath of Khan or The Mummy movies, it grows to approximately an inch long and it’s head bears a very impressive and sizeable pair of sickle-like jaws (mandible) that have numerous sharp, hallow projections.  In fact, their mandible is so large that it makes walking difficult and so they will typically walk backwards. They seize their prey by injecting poison that paralyzes it.  Additional digestive enzymes are injected to break down internal tissue of its prey.  It then sucks the liquefied contents of it’s preys body and then flicks it out of the pit.  The larva then repairs the pit and waits for it’s next victim.

Ant Lion larvae eventually pupate in the soil.  As scary as their adolescent stage appears, the adult resembles a dragonfly or damselfly except the Ant Lion folds it’s wings back in a tent-like fashion.  They also have longer, prominent, clubbed antennae and different type of wing venation.  Adults are rarely encountered in the wild as they are nocturnal.  They feed on nectar and pollen.

Ant Lions are often included in lists of beneficial insects, no doubt because they prey upon ants, a common pest to humans.

You can find lots of these cone shaped traps in the Deschutes Campground and along the Tam A Lau trail.  Also in the Crooked River Day Use Area.  You can pretend to be prey by gently dropping a small piece of stick and watch them kick the sand out to knock the prey down into the bottom of the cone.  Please be respectful of park wildlife and do not step on or destroy the traps.  Ant lions do not typically bite humans but they can if they are scared.

Perseid Meteor Shower

Perseid_bright_8-12-2012_Stefano_De_Rosa_Italy.jpeg

It’s time for the annual Perseid Meteor Shower light show. This show will burst into light as the Earth passes through the tail of Comet Swift-Tuttle. Between July 17th and August 24th you can find front row seats for this astronomical wonder. Picture icy balls of space debris (meteoroids) hurtling through the sky at hundreds of miles per hour. As they reach Earth’s atmosphere they burn up and streak across the night sky; much to the wonder and delight of the humans below. But this year isn’t just any year. In 2016 the Perseids will be in “outburst,” which means that they will appear at twice the rate – that’s right folks, at the peak on August 12 you may see as many as 200 falling stars an hour. It hasn’t been this incredible since 2009!

This map shows the radiant of the Perseid meteor shower from the constellation Perseus in the northeastern sky during the meteor display on August 12, 2015.  The Perseids appear to radiate out from a point on the border of constellations Perseus and Cassiopeia.  Credit:  Sky & Telescope Magazine Illustration

Comet Swift-Tuttle is the largest object known to repeatedly pass by Earth; its nucleus is about 16 miles (26 kilometers) wide. It last passed nearby Earth during its orbit around the sun in 1992, and the next time will be in 2126. But it isn’t out of sight, out of mind, because Earth passes through the dust and debris it leaves behind every year, creating the annual Perseid meteor shower.

The key to seeing a good meteor shower is to find a dark, wide open sky with few trees to block the view. Prepare to sit outside for a few hours.  Bringing a comfortable lawn or camp chair, a warm blanket and some hot chocolate make it much more fun.  It takes thirty to forty-five minutes for your eyes to adjust to the dark; the longer you are outside, the more you’ll see. Don’t turn on flashlights or lanterns with white light, it will diminish your night vision.  If you need light, cover your lens with red cellophane.   Then sit back, relax and wait… A rate of 150 meteors per hour, for instance, means two to three meteors per minute, including faint streaks along with bright, fireball-generating ones that are truly ooh & ahh-inspiring.

If you are camping at The Cove, try looking on the Crooked River side of the park up high.  Find a spot facing Mt. Jefferson, it is particularly awesome if the Island is in between, looking west and enjoy!  If anyone gets great pictures they’d like to share, we’d love to talk to you.  Contact Ranger Erin Bennett 541-546-3412 x 229 or erin.bennett@oregon.gov

 

 

Algae Update at Lake Billy Chinook

Health Advisory Lifted – New water monitoring has confirmed that the level of blue-green algae toxins are below guideline values for human exposure.  It is safe to boat/swim in the Crooked, Deschutes and Metolius River Arms of Lake Billy Chinook at this time.

The Oregon Health Authority recommends that people continue to be cautious with their pets in the lake because toxins are still above the very low exposure levels established for dogs. (Health Advisories may still be in effect at Perry South)

Why is the lake green?

The term “Algae” refers to a broad scope of organisms.  Algae can range from the microscopic single celled organisms that can be floating in a lake, to large seaweed plants that are found in the ocean, like Giant Kelp.  Your common lake variety of algae is known as green algae.  (This is different from the toxic blue-green algae, which is actually a form of bacteria known as Cyanobacteria, that can make some people and animals sick.)

Single celled Green Algae, photo credit http://www.algae.info

Green algae is the single cell variety of green algae that most commonly turns Lake Billy Chinook green.  These tiny little micro-organisms live off of the nutrients in the lake and use the sunlight to photosynthesize, much like the plants and trees above the water.  These little organisms contain large amounts of “chlorophyll,” which is a pigment that makes all plants green.  (Chlorophyll is the essential pigment that allows plants to photosynthesize sunlight into food.)

Green Algae in Lake Billy Chinook

When the weather and the water temperature warm up, typically in late spring or early summer,  the entire lake can resemble a huge pot of split pea soup.  This occurs when the number of algae organisms begin to reproduce at an astounding rate.  These algae are able to reproduce because there is an excess of nutrients found in the water.  The algae can become thick and doesn’t smell very good.  Algal blooms are a naturally occurring phenomenon, and are essential to the overall health of the lake.  This excess bloom of plant life provides tons of food for other microorganisms and fish.

 

Algea at Lake Billy Chinook Update

As of Saturday, July 9, 2016 –

Deschutes Arm – No advisories at this time
Crooked River Arm – Swimming Advisory, use caution; additional testing in process

Additional information will be posted if and when conditions change.
