Watching Zion Grow

The latest installment of Accretionary Wedge is a call to write about the “most memorable/significant geologic event that you’ve directly experienced”. This will be my first contribution to Accretionary Wedge, so if I’m doing it wrong, someone please let me know!

When I first heard the topic, I thought “well, I grew up in Southern California, so I’ve experienced lots of geologic events.” I’ve experienced more earthquakes than I can remember.

The 1994 Northridge quake knocked me out of bed.

I felt the 1987 Whittier Narrows quake while walking to school.

Then there was the one (unnamed, as far as I know) that occurred while I was in the shower, and my 14 year old self panicked at the thought of having to run outside naked.

I was in San Francisco a few weeks after the 1989 Loma Prieta quake, so while I didn’t feel it personally, I saw the aftermath up close.

I was at Mt St Helens a few months after the 1980 eruption. Again, not a direct experience of the event itself, but that experience is certainly something I’ll never forget.

(The real question here is why I didn’t become seriously interested in geology until a couple years ago!)



A Toe in Salt Lake, Part One

Leave a comment

I just realized that it has been a month since I posted a blog entry. I am so very negligent. I could give you a million reasons, like the fact that I’ve driven through 21 states (and into another country!) since the events of my last entry. Or that I’ve been sick and drunk on Nyquil (except when driving) for the last week. I could tell you that this particular post has been sitting on my computer in partially-finished draft form for several weeks. But I know that none of those sorry excuses can assuage your anguish over going a whole month without me waxing prosaic on topics I know next to nothing about. So I’ll give you part one of this post now, and I’ll finish it up soon and post the rest.

This time the title is accurate, because ewwwwww. But we’ll come back to that.

Just like there was ancient Lake Lahontan in Nevada, there was ancient Lake Bonneville in Utah. And driving through western Utah, you see evidence of it everywhere. At its maximum, it was a huge lake.
