I was just reading about how the Kathmandu valley used to be a lake, up to around 15,000 years ago. No wonder it got hit so hard. The soil acts like jello when its shook that hard.

The last massive quake in that region was in 1934 at mag 8.3. And since then, Nepal's population has increased 5 times.

I personally don't understand how a science minded individual couldn't have an interest in physics and astronomy. Everything else is a derivative.

Yes, the drought is bad this year, and has been for four years running. But the cliffs will always be there...
There are so many moments when I want to deny the reality of the California drought. It has been relentless, the winter air warm and dry, the soil crunching under my feet at a time when it should be muddy and covered with veg...

But there's a catch...
During our field trip last weekend, we stopped briefly at a mineral show in the Sierra foothills. I wasn't going to buy anything, but then I saw some specimens that made my jaw drop, and they were available for an incredibly ...

Just imagine the sales spiel of a Raptor real estate agent. Every room has a view!
The Great Valley is a great place for raptors. Despite the intense disruption of the natural landscape, they've benefited in some ways. For one, they have received the gift of thousands of potential nesting sites in the form ...

One of the birds seen today on Table Mountain
I took a hike to the top of Table Mountain in the Sierra Nevada Mother Lode today. It wasn't a birding trip, but there were a few of them about, including some swallows that were moving very fast over the grassy meadows. One ...

Yosemite hawks, one at Sentinel Dome and another on the Tuolumne River.
There is a dead snag above the Tuolumne River near the bluffs of the future river walk park. I have to give it a look every time I wander by because there seems to be a different bird perched there every time. Sometimes a Sta...

They will be moving into the hills soon
Western Bluebirds (Sialia mexicana) run hot and cold on my walks. Sometimes weeks will pass and I won't see any at all, and then I'll see several of them within a day's time, and in multiple locations. In a matter of weeks I ...

Tree Swallows along the Tuolumne River
In my usual life as a geologist and professor, I often describe to my students the secret of mineral or fossil hunting: once you've seen something, however difficult to see, you'll start seeing it everywhere. I've spent my en...
