A winter walk along West Fork Oak Creek

It’s been cold around these parts lately. How cold? Well, we’ve seen -24ºF in Bellemont, -19ºF in Tusayan, and -9ºF in Flagstaff. These are all northern Arizona communities that are used to the cold — but not for this many days in a row. This is the coldest 5-day period in Flagstaff in over three decades.

There are some benefits. With prolonged cold some of the streams in the canyons will freeze. With this in mind, we took a hike up West Fork Oak Creek. The trail was snow packed and icy. Wisely, we all had foot traction gear including instep crampons and microspikes.

The trail crosses the creek numerous times and the first few crossings were tricky but doable. That is, the logs and/or stepping stones were ice covered but sure footing could be found using care and caution.

One of stream crossings, though, stymied us. For whatever reasons, the water and ice level had increased substantially in this location so that all the stepping stones were well under water and ice. And the flow of water had become concentrated along one side of the channel so that the ice was eroded. After studying it for awhile, we reluctantly agreed that the risk of crashing through the ice was too great. We turned back.

In previous years we had easily moved through this crossing and many others farther upstream including the “subway” passage. We had hoped to make it this far and, possibly, even farther upstream. It wasn’t to be.

Still, it’s never a bad day when you are out hiking with no one else around except your friends in an environment not often experienced by most.

“Science experiments” with boiling water on a cold day

It seems that we get extraordinarily cold mornings on New Years Day. It was -17°F for a low temperature in Bellemont, Arizona today. Two years ago, on New Years Day 2011, it was -30°F. Both times we had fun tossing boiling water into the air and watching it freeze before it hits the ground.

Yeah, sure, folks up north do this all the time in the winter. But, remember, this is Arizona!

Which freezes faster, hot water or cold water?
