Stratigraphic Photogrammetry: Part 2 – A Quick Proof of Concept

I’ve been moving along, making progress on my methodology for stratigraphic photogrammetry. I don’t remember just off of the top of my head, but I think that the actual title of the paper is something like A Method for the Use of a Non-Metric Digital Camera in Stratigraphic Photogrammetry. I present the paper (which I will post […]

Stratigraphic Photogrammetry: Part 1 – Calculations for Photometrics on the Olympus C-750

For the last few months, I have been working on a methodology for using terrestrial photogrammetry techniques in capturing stratigraphic profiles. The original idea for this came on the Wenas Mammoth dig (which I wrote about on 10 August 2005), when we were not sure, at one point, if our trench, cut into a wall […]

Definitions of Landslide Features

I have spent a lot of time lately learning about mass wasting. No, that doesn’t have anything to do with drugs. Mass wasting is the downslope movement of slope material under the influence of gravity. Mass wasting shows up as rock falls, landslides, and various types of flow (mud flow, earthflow, debris flows, etc.). I […]

Desirable Watershed Conditions

The capture, storage, and beneficial release of water. The Watershed Manager’s Mantra To achieve the watershed manager’s goal of capturing, storing, and releasing water in a safe and beneficial way, he must: Maintain vegetation on the site sufficient for absorbing the energy of precipitation (so raindrops hit leaves and dissipate their energy – raindrops splatter soil, […]

In Search of a Better Scraper

One of my main pedological field tools (pedology is the science of dirt), other than my trusty shovel, is the “scraper.”  The search for the perfect scraper is the focus of all my gear-hunting efforts.  The scraper is used when looking at a soil profile to get a clean, flat, clear soil face to look […]
