  • Scenic view of the Willamette River, bank full from spring snowmelt.  Looking south from George Rogers Park in Lake Oswego.  The concrete structure in the river was a log hoist built in 1905 by Crown Willamette Paper Company and operated until the 1920s.  More recently, the private owner abandoned an attempt to improve it as a residence and today it lies abandoned.

  • A mini-series following my 44mm-high Homies character Pelon, where he poses for photo ops at potholes on the streets of Mount Tabor Park.<br />
Leadership fixes potholes, not patching.<br />
Chronic neglect of Portland’s streets is manifesting in the burgeoning number and size of dangerously large potholes across the city.  Here, pothole road damage is seen in Mount Tabor Park, Portland, Oregon. <br />
Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section…or lack thereof, as in this case.  Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  At this pothole, the asphalt layer is thick; confirming this road has received an overlay, but perhaps covering up this pothole without first repairing it. The base course layer is hard to characterize because the quantity of water present. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock.  This dangerous pothole, in the traveled way and where pedestrians cross, can be repaired by cutting out and reconstructing, but simply patching or overlaying will rapidly lead to a repeat failure, preventing a level of service – or service life – that should be reasonably expected of it.<br />

Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  The asphalt layer is minimal; confirming this road never received the maintenance originally planned. The size variation of aggregate chunks in the base course layer tells the story of a roadway constructed originally from well-graded materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock.  The breakup of pavement behind and to the left of Pelon – at the gutter – suggests that poor drainage played a role in this failure, and absence or repair has allowed water to saturate the base layers and complete the failure.  This road has failed due to neglect and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.<br />

  • Skinner Butte Columns is a small, well-established rock climbing area in a downtown city park in Eugene, Oregon, USA. The rock is columnar basalt formed in a slow-cooling magma intrusion, resulting in relatively uniform polygons and rock of high density and excellent quality.  The cliff was mined in the early 1900s, but the more fractured, unstable face resulting from mining operations has been blanketed with chainlink fence to prevent climbing on the unstable rock.

  • The southern African Bearded Vulture (Gypaetus barbatus) - or Lammergeyer - is currently endangered and likely to become extinct.  Originally common throughout Lesotho, the Free State, Eastern Cape Province and KwaZulu-Natal (along the Maloti-Drakensberg mountains), the Bearded Vulture now only breeds and forages across a fraction of its original range. Current (2011) population estimates are in the region of 100 breeding pairs, down from over 200 pairs 25 years ago.  Here, this rarely-seen vulture-like eagle of Africa catches the sun's first rays while the grassy slopes of the high Drakensberg remain in deep shadow.

Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  The asphalt layer is minimal, confirming this road never received the maintenance originally planned. The river-rounded pebbles of the base course layer tell the story of a roadway constructed originally from deficient materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock – a crushed and sieved mix from those same pebbles would suffice.  Finally, from the moisture visible in the pothole, and the shape of terrain at the road shoulders, it is clear that poor drainage has contributed to the failure of this road.  The conclusion is unequivocal; this road has failed and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.<br />

  • Outlet valve at Bull Run Lake 968m (3,175ft), with Mount Hood 3,424m (11,234ft) beyond. This is the highest reservoir in the Bull Run Watershed and is celebrated for the high purity of its water. This is the origin of Portland's drinking water, which flows by gravity to the Mount Tabor reservoirs before entering the City's water distribution network.

  • A mini-series following my 44mm-high Homies character Pelon, where he poses for photo ops at potholes on the streets of Mount Tabor Park.<br />
Leadership fixes potholes, not patching.<br />
Chronic neglect of Portland’s streets is manifesting in the burgeoning number and size of dangerously large potholes across the city.  Here, pothole road damage is seen in Mount Tabor Park, Portland, Oregon. <br />
Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section…or lack thereof, as in this case.  Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect.  The asphalt layer is minimal; confirming this road never received the maintenance originally planned. The large cobbles of the base course layer tell the story of a roadway constructed originally from poorly graded materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock.  The conclusion is simple; this road has failed due to neglect and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.<br />

  • Giant lobelia (Lobelia deckenii keniensis) foreground, lichens and giant tree groundsels (Senecio keniodendron) - one in bloom - thrive in the high-precipitation, high-altitude  equatorial climate of Mount Kenya.  These plants are at 4375m (14,355ft), below Midget Peak 4700m (15,420ft), shrouded in afternoon mist.  Nikon F4. 28-70/3.5D. Kodak E100SW.
