Hoodoos are one of the iconic images of southern Alberta, along with endless fields of canola and the steady rocking motion of a pumpjack. While small hoodoos are common in the badlands around Drumheller, larger ones are a sight to behold.
Formed where a harder type of rock sits atop the softer sedimentary rock below, the cap protects the underlying rock from wind and water erosion, producing a column. A hoodoo that has lost its cap is vulnerable, as it will undergo accelerated rates of erosion, causing these to be some of the more fragile landmarks.

Dinosaurs.
If you have never been to the Royal Tyrrell Museum outside of Drumheller, you really should go. Situated in the badlands of southern Alberta, and devoted entirely to paleontology, it is a dinosaur lovers dream.
The badlands of Alberta produce a seemingly astonishing number of fossils. (I say 'seemingly' because there isn't really a greater number of fossils here compared to anywhere else... it's just the erosion of the rocks greatly increases your chances of actually finding them.)
Fossils are uncommon because the circumstances that lead to their formation tend to be uncommon. In order for an organism to turn into a fossil, it needs to be covered in sediments very quickly, which usually involves ending up at the bottom of a lake or in a tar pit. This needs to happen in an area where the remains will not be disturbed (you won't get much in the way of fossilized remains if scavengers carry off all the parts or they get washed away) and, depending on the type of fossil, in an environment where decay happens very slowly, or not at all.
Millions of years ago, Alberta was at the bottom of an inland ocean. (It has actually been submerged several times, leading to fossils from all different time periods like the Cambrian Burgess Shale and the Triassic dinosaurs.) This ocean contributed to the large amount of sedimentary rock in the area, and, along with lots of time and several glaciers, helped turn Alberta into the fertile, fossil-filled prairie it is today.

Farming.
The animal kingdom is a pretty sweet place. We (humans) tend to think of ourselves are special and very different from the other creatures we share our planet with, but it's really not that true.
While in Drumheller this weekend, I encountered something pretty neat. Dom, Heather and I were hiking in the Badlands when Dom noticed a strange looking sage bush with little black things all over it.
Turns out the black things were aphids. Aphids are little insects that suck the sap out of plants (making them the bane of gardeners). When the aphid taps into the sap-containing phloem in the plant, the high pressure phloem sap is forced through the gut and out the other end of the aphid. Sounds gross, right? This is known as honeydew, and it's irresistible to ants.
Crawling all over the aphids on the sage bush were ants. The ants are farmers of sorts; they eat the honeydew produced by the aphids, and in turn protect the aphids from hungry invaders in return. This is an example of a mutualistic relationship, one where both parties benefit from the interaction.

Glass.
One thing I have been wanting to try for a while is etching glass. Since I have lots of time on my hands this week, it seemed like a good time to try! So I picked up some supplies at the craft store (hint to my fellow teachers... Micheal's offers 15% discounts to teachers! You have to ask for it at the check out, and sometimes they want to see some form of proof - I keep my ATA card in my wallet for such occasions... since I've never found any other use for it.)
Whatever surface the cream touches will be etched, so you need to be careful when applying it. As well, the etching cream is extremely toxic and hazardous, so this activity is best not done with the kiddies. (The particular product I used, Armour Etch, is very effective, but covered in HHPS warning symbols for poison and corrosive chemicals, and the MSDS is enough to give anyone who knows how to read them the willies. You know it's good stuff when they print the Poison Control Center phone number on the bottle.)

Watermelon Lemonade.
| "The night is young, Arthur, and we have umbrellas in our drinks." |
I am pretty useless in hot weather (so perhaps my chosen profession and location are good ones.) so I've been trying to find little things I can do to escape the heat. I found this recipe on Pinterest and thought it would be an excellent way to combat the heat, and use up some of the strawberries I had in my fridge (and take my new immersion blender for a test run... it's pretty fantastic!).
It was pretty tasty! I scaled it down from what they have in the actual recipe, but probably should have used more water/sprite because it was a bit thick. Quite refreshing on a hot, humid day!

Inconceivable.
Latest art installation in the house - a birthday present from the awesomely talented Nick!

Fried Pickles.
I love pickles. This is no secret. Still, I was a little skeptical about this recipe that I encountered on Pinterest. Fried pickles? Really?
Goodness, they were delicious. I made a small batch to test them out, and ate them all rather quickly. The only change I made to the recipe other than halving the batter was that I used dill pickles. I imagine the jar of sliced pickles the author refers to is bread and butter. I'm a dill girl all the way through.
I used two cooling racks to achieve the double sided broiling as the panko crumbs were a little fragile. When it was time to flip them over, I placed the second cooling rack on top, and flipped the whole thing at once. Worked like a charm!
