The folks at Logiteasy.com have created a great little free online tool that will calculate a USCS soil classification (ASTM D 2487 / ASTM D 2488) based on the percentage of your components and fines type. It's drop dead simple to use with sliders and buttons. [Source: Use the tool for free at LogItEasy.com. Image: Logiteasy.com]
Every tunneling machine needs its cutting tools replaced every now and then. But the challenge is keeping a giant machine sharp while a wall of waterlogged earth looms in front. Welcome to the world of hyperbaric interventions, where crews used compressed air to stabilize the ground and safely complete this high pressure work. This video takes you 200 feet underground for a rare look at hyperbaric work inside Seattleâ€™s SR 99 tunneling machine, Bertha. [Source: WSDOT YouTube Channel. Image: YouTube]
How do you get the most out of the geotechnical data your company or agency spent so much money to obtain? GeoPrac sponsor Keynetix is an expert at answering just that question, and their latest blog post has 5 great tips on how to maximize the use of your data. This is some very actionable stuff for geotechnical engineers, and a must read for anyone who works with subsurface data in gINT, HoleBase or other geotechnical software.

Earlier in February severe rain caused the Oroville Dam in Sacramento to reach capacity. The dam is an earth fill dam approximately 770 feet high, making it one of the tallest dams of this type in the Country. On February 11, water began flowing over the emergency spillway, which prior to that point had never been used, and caused erosion at the base of the weir, threatening to undermine the wall at the top of the spillway and potentially cause a catastrophic failure of the dam. Local police officials ordered a massive evacuation of residents downstream of the dam. The dam didn't fail and this week flow across the main spillway was stopped to allow officials time to evaluate the damage. The LA Times article linked below has a good summary of many of the issues that led to this crisis. And this article discusses the most recent developments with the shutting off of the flow at the spillway to evaluate damage. [Source: Read more about the Oroville Dam at LA Times. Image: USA Today]

Our colleagues over at Geoengineer.org put together a great video compiling some of the more interesting stories of 2016 for all of us geotechnical nerds. Check it out! [Source: Geoengineer.org YouTube Channel. Image: YouTube]
RockWare, the makers of RockWorks and LogPlot geotechnical software, have released a free online tool to convert between different coordinate systems. You can convert to and from State Plane coordinates using a NAD27 datum, and geographic latitude and longitude with a NAD83 / WGS84 datum using a pretty simple interface. There are probably a few other coordinate systems built in there as well. You can visualize your points immediately on a Google Maps interface. You can also plot up an elevation profile if you like.
