One year ago today: first icebergs, first Antarctic landing, first penguins!

Highly Allochthonous | 21 December, 2014
A fortunate consequence of a calmer Drake Passage is that our progress across it was quite speedy. When we woke on the morning of the southern hemisphere's summer solstice, we had nothing but steel blue seas and seabirds for company.

Greed explained: J. Paul Getty, Aristotle and the Maximum Power Principle

Resource Insights | 21 December, 2014
Regular readers know I often write about energy, and while this piece may not at first blush seem like an energy story, you'll soon see that the quest for an ample supply of energy is, in fact, at the heart of human greed.

If I ever become ridiculously rich, I'm going to open up a geological theme park. Can you imagine the rides? Earthquakes, volcanoes, landslides, and more - all very exciting. And educational. I think we could make it work, don't you? Imagine the field trips!

One year ago today: crossing the Drake Passage

Highly Allochthonous | 20 December, 2014
Even starting off as far south as Ushuaia, it's a long way to Antarctica - almost 1000 km of open water. We got a peak of the chart below whilst touring the bridge of the Corinthian - they have computer charts nowadays, of course, but as geologists we still have a soft spot for the paper variety.

Geo 730: December 20, Day 719: Timberline Trail

Outside the Interzone | 20 December, 2014
Timberline Trail circumnavigates all of Mount Hood, as the name implies, near timberline. Here it can be seen descending into the upper valley of the White River (unless you're taking the trail clockwise, in which case it's ascending from that valley). I did consider walking down there, but decided I didn't want to make the climb back up. According to the PDF at the link up front, the trail is "only" 36.6 miles/58.9 kilometers- I could've easily done it in two days, or a leisurely three, 30 years ago, but these days, not so much. This photo also does a good job of showing how persistent the snow is. We were probably right about 6000 feet here (the lodge is at 5960 feet), and that little finger of snow field up the valley appears to be below, or at least close to, our elevation.

Grizzly Peak

Oakland Geology | 20 December, 2014
Grizzly Peak is the highest point in Oakland, at 1754 feet elevation (sources differ). As you approach it on Grizzly Peak Boulevard, it seems to loom quite high.

Geo 730: December 19, Day 718: Upper Salmon River

Outside the Interzone | 20 December, 2014
At the end of the dry season, this modest stream is barely a trickle. However, according to Wikipedia (see stats box on upper right), the Timberline area receives an average of 45 feet of snow each winter. (Note this is not the amount of snow on the ground at any time; it's total snowfall.) During spring melt, or during warm rain events, such as we're having today, Dec. 20, 2014, this small stream certainly swells to a torrent. Looking at all the loose rubble in and around the water, and noticing that the banks of the canyon are at a consistent angle of repose, it's easy to see how those high water events can lead to debris flows such as we witnessed earlier in the day at the White River Bridge. All this loose stuff is eager to get downhill.

I Have Some Exciting Trips Planned in 2015 - Join Me!

Earthly Musings | 20 December, 2014
Many of the readers of this blog have traveled with me before to learn a bit about earth history and the evolution of landscapes. In 2015 I have a fantastic line-up of trips planned, both internationally and here in the Southwest. You can view a pdf of all of my trips here. There is no better way to travel than with your own personal geologist to explain what you are seeing. I hope to see you in 2015!

One year ago today: our Antarctic voyage begins

Highly Allochthonous | 19 December, 2014
You may recall that last Christmas, your intrepid bloggers managed to find ourselves on the trip of a lifetime to the Antarctic. We're pretty sure that Geokid was Santa's most southerly delivery on Christmas Eve. We have posted the odd photo of our trip, but somehow in a very hectic year we have not shared as many of the amazing sights, sounds and memories of our cruise around the Antarctic Peninsula as we would have liked - and we'd like to change that. So over the next few days, we're going to indulge in a bit of time travel and show you what we were up to this time last year. Life is still busy, so there's no guarantee of much insightful commentary, but quite frankly, it's mostly unnecessary. And I think we can guarantee penguins. Lots of penguins.

Accidental Remediation | 19 December, 2014
I occasionally see badly-written reports that will be read and picked apart by other stakeholders, and  bidders who blatantly ignore proposal requirements. I have also attended meetings with technical experts who had no idea what they were supposed to discuss.
