Was reminded of these controlled burn photos from last year, so thought I'd post a couple of my favorites....
Controlled burn by Dane County Park personnel at Cam-Rock Park in Cambridge, Wisconsin. April 28, 2009.
Part of the woods caught on fire at Stony Creek Metropark on April 1, 2010. The green in the background is the prairie area that also burned.
There was a controlled burn of my favorite prairie at the mountain bike trails/Shelden Estates area of Stony Creek Metropark on April 1, 2010.
It looks like some of the fire spread to the woods. I guess that makes it uncontrolled.
An article about the burn appeared in the Oakland Post:

From the Behind-the-Scenes Tour around Tower Bridge: Towers, high-level Walkways and Victorian Engine Rooms down to its hidden depths, normally out of bounds to the public...views from the Glass Floor and high-level Walkway, then the original steam engines, accumulators and boilers in the Victorian Engine Rooms...the Bridge’s operational areas including the Control Cabin, Machinery Room and the immense Bascule Chambers, which house the 422-ton counterweights.
Built between 1886 and 1894, the Bridge has spent more than a century as London's defining landmark, an icon of London and the United Kingdom.
A huge challenge faced the City of London Corporation - how to build a bridge downstream from London Bridge without disrupting river traffic activities. To generate ideas, the Special Bridge or Subway Committee was formed in 1876, and a public competition was launched to find a design for the new crossing.
Over 50 designs were submitted to the Committee for consideration, some of which are on display at Tower Bridge. It wasn't until October 1884 however, that Sir Horace Jones, the City Architect, in collaboration with John Wolfe Barry, offered the chosen design for Tower Bridge as a solution.
It took eight years, five major contractors and the relentless labour of 432 construction workers each day to build Tower Bridge under the watchful eye of Sir John Wolfe Barry.
Two massive piers were built on foundations sunk into the riverbed to support the construction, and over 11,000 tons of steel provided the framework for the Towers and Walkways. This framework was clad in Cornish Granite and Portland Stone to protect the underlying steelwork and to give the Bridge a more pleasing appearance.
When it was built, Tower Bridge was the largest and most sophisticated bascule bridge ever completed ('bascule' comes from the French word for 'seesaw'). These bascules were operated by hydraulics, using steam to power the enormous pumping engines. The energy created was stored in six massive accumulators, meaning that as soon as power was required to lift the Bridge, it was always readily available. The accumulators fed the driving engines, which drove the bascules up and down. Despite the complexity of the system, the bascules only took about a minute to raise to their maximum angle of 86 degrees. Find out more about this process.
Today, the bascules are still operated by hydraulic power, but since 1976 they have been driven by oil and electricity rather than steam. The original pumping engines, accumulators and boilers are now on display within Tower Bridge’s Engine Rooms.

My first attempt at using a strobe in landscapes, and I think I'm hooked. SB-28 off camera at 1/3 power with 20" exposure to burn in the rest. It was close to total darkness.
Control House at Gatún Locks, Panama Canal, 1965. Each control tower has a model board of the lock system governed by that tower. Note the wraparound deck, where staff often ate lunch. Approaching at the higher level of the canal.

Heading back to the hotel after a delicious Chinese lunch, we passed this delightful moose, in front of the Blue Moose Tavern & Restaurant in Bolton Landing, New York, USA (near Lake George). As I looked at it closely & took several photographs, we realized it was a robotic moose. Who knew?

My house will never be neat & tidy while my kids are young: I have accepted that. When I found this doll hanging off the picture ledge I couldn't help but smile: what the heck is she doing up the of all places on a picture ledge? 73:365
Looking across the mouth of the Cooks River over at the old control tower along with the popular planespotting site, The Beach. I was worried that the planes would be a bit too close for me to photograph with my large lens, so I stuck to the Mascot rock jetty. Not to mention walking over to The Beach would've added ten minutes to my walk all the way from Banksia railway station.
