Geology Photo of the Week # 21

The photo of the week today is of a Canadian National Heritage Site. It is located just outside of Dawson City, Yukon and is unassumingly called Dredge 4.  Those of you who read this blog regularly will know that I am a huge fan of the Yukon, which is the site of my field work, and love talking about the gold rush history of the region. Very few things embody this history better than Dredge 4…the Discovery Claim may be the only better spot. Dredge 4 really represents the industrialization of gold rush mining. Dredging took backbreaking labour once done by men with picks and shovels and turned it into a truly industrial operation. This method of mining very effectively purged what gold was left in the Klondike district. However, placer mining of this scale had a huge impact on the local environment as some of the other photos will show. However, despite the impact the dredge and its mark are still incredible relics of gold rush history.

The next picture shows a schematic of how a dredge worked. The bare essentials are that the dredge would move along flooding the land beneath it so that it would float and all the while scooping up the gold bearing gravel below it. The gold was extracted inside and the cleaned gravels were “pooped” out the back of the dredge in large piles that litter the landscape today.

GeoSphere: In Review

After two years of regular geology blogging I was thinking it might be fun to highlight the posts that I think are my best work as well as the ones that have been the most popular…they are not necessarily the same. This just goes to show it is impossible to predict what the collective consciousness of the geoblogopshere or the geotwitterverse will like the best. Some of these posts come from my old blogging home, which is just a regular blogger site so the links will take you there. Others are more recent and were posted on my EGU blog. I hope you enjoy this little blast from the past.

This EGU blog went live on October 1, 2012 and in that time it has had 2,530 visits of which 66% were by unique visitors, who spent on average 3 minutes on the site, which I think/hope means they actually read something. The most viewed pages have been:

There have been visits from 73 countries so far. Interesting ones include: Laos, Faroe Islands, Iran, Oman and Mauritius. The countries that have made up the largest proportion of my visits have been the United States with 39%, Canada 20% and the UK 11%, Germany 5% and Australia 4%.
My old blogging home, pre EGU, has received 59,503 pageviews since it went live in early February 2011. The numbers for this site come from Blogger stats since I didn’t start using Google Analytics until last year. The most popular posts there have been:

The countries that liked this site the most are pretty much the same as the EGU site, which I hope means I pulled a few people over with me!  The United States makes up 62% of the pageviews, Canada 7%, UK 5.5%, Australia, 2% and Russia 1.5%. I guess it should’t come as a surprise that most of the views for both sites come from North America, where I am located and English speaking countries, the language the blog is written in. I suppose I could read a bit deeper into and point out that both sites have a lot of countries with resource driven economies in the top 5, but that might be too big a stretch since I suspect it has more to do with the language.

 

My favourites

My personal favourite posts over the past few years are mostly on the most viewed lists above. It is hard to pick just one that I like the best though and there are a few that I wrote early on in my blogging career that only got a few pageviews, but I think are pretty interesting. Here are my top 5 in no particular order.

The Odyssey and Geology – The Search for Ithaca – this post summarizes a Nature Geoscience paper that surmises the legendary island of Ithaca has been lost in plain sight for the past few thousand years…

The Art of Geology – this was an Accretionary Wedge topic and for whatever reason I felt inspired and feel that I made a pretty solid contribution to this one.

The Media Portrayal of Geologists – This is a funny one….my apologies if not all the videos work…they were uploaded 2 years ago.

Back to Basics on Groundwater – This one is a really simple primer on groundwater and groundwater flow. It has proved to be extremely popular so far…maybe I should write another one…

It’s all about scales – I had been planning this one for some time and I have to say it turned out better than I had expected.

Bonus Favourite: The Wooden Wall – the story of how a silver mine saved the Greeks during the Persian Wars…I enjoyed doing the research and looking a mineral pics.

Things I’ve Learned

By the way, to put some of these numbers into perspective I also monitor a website about a book called Breaking the Vicious Cycle. It was written by my grandmother and is in its 14th printing right now having sold well over a million copies and been translated into several languages. Her website receives between 1,500 and 3,000 visits per day!!! It has gotten 266,125 visits since October 1, 2012 and 1,471,484 pageviews. If I ever get too cocky about getting a measly 2,530 visits I just think about her website and that helps restore me to an even keel.

All in all I am very happy with how being a geology blogger has gone and am extremely happy to be part of the EGU blog network. I think blogging has been an enriching experience that has allowed me to connect with fellow geoscientists from across the globe and expand my network. Not only that, it has allowed me to hone my writing skills, and given me a soapbox of sorts from which to expound my views on geoscience communication and outreach. I certainly intend to continue blogging in the future and I thank any readers who do stop by for your encouragement and support.

Geology Photo of the Week # 20 – Feb 3-9

This week we have a photo of the something that has been on my mind a lot for the last little while and will continue to be on my mind in the comings years months weeks. Of course I am speaking of lab work and particularly the new iodine extraction line that I have been developing. Over the past few months I have had a 0% success rate with this damn thing. However, thanks to the fresh ideas and experience of a new radiochemistry professor in our department I have now had some success. In fact, I was so excited by this success that I did one of these:

Anyway, now that some progress has been made it is time to duplicate, refine and start using the line for actual samples. Thus, the photo of the week is a picture of the line that I now get a warm fuzzy feeling looking at as opposed to the former sinking and depressed feeling. Hopefully it lasts…..

My iodine extraction line for solid samples.

Cheers,
