- Charlevoix, Quebec – OCTOBER – ADDITIONAL SHATTERCONE DATA
Yours truly pointing our an in situ shatter cone in the Charlevoix impact structure.
- Charity Shoal, Lake Ontario Canada – OCTOBER – ADDITIONAL DATA/IMAGE

- Sudbury, Ontario – OCTOBER – ADDITIONAL DATA
Differentiated impact melt sheets may be a potential source of Hadean detrital zircon
- Bloody Creek, Nova Scotia – SEPTEMBER – ADDITIONAL DATA
The North structure: evidence for a second possible impact event at the Bloody Creek site, Nova Scotia, Canada Atlantic Geology Volume 51 (2015)
- Prince Edward Point, Ontario – August
I was approximately approximately 1000′ above Lake Ontario admiring the clarity of the water when I noticed this circular structure. So, I just had to go there and see for myself if the structure had any impact characteristics.
The Manitou Islands complex from my bird GOZooM from approximately 2000′ above the lake.

- Bow Alberta City, – June
The Bow City Impact structure from the north taken from approximately 4000 feet above ground level. “Ground zero” is image centre.
- James River, Alberta – June
The James River structure from the south east approximately 4000 feet above ground level. “Ground zero” is image centre.
- Purple Springs, Alberta – June
The Purple Springs structure from the north from approximately 4000 feet above ground level. “Ground zero” is image centre.
- Dumas, Saskatchewan – June
The Dumas structure from the north west from approximately 4000 feet above ground level. “Ground zero” is image centre.
The Croker Island Complex from the north, Fox Island is in the foreground with Croker Island immediately under the wing representing the “central peak” of the structure.
- Skeleton Lake, Ontario – June
- Hartney, Manitoba – June
The Hartney structure from the north west taken from approximately 4000 feet above ground level. “Ground zero” is image centre.
- High Rock Lake, Manitoba – June
The High Rock Lake structure from the north. The “point of impact” is in the immediate foreground right with High Rock Lake in the background.
- Brent, Ontario – June – IMPACT METEORITE CLASSIFICATION
- Red Wing, North Dakota – May
- Viewfield, Saskatchewan – May
Viewfield – the superimposed circle illustrates the position of the buried crater. This image, aimed looking west at the approximate point of impact, was taken from GO ZooMat approximately 2500 feet AGL.
- Alsever Lake, Ontario – May
- Hudson Bay Arc – October
Lithospheric architecture and tectonic evolution of the Hudson Bay region
Kraus et al, Nanosecond formation of diamond and lonsdaleite by shock compression of graphite, Nature Communications 7, Article number: 10970 14 March 2016
- Slate Islands, Lake Superior – May – RASC 2013 expedition
This Google Earth image of the Slate Islands impact structure depicts the crater that is underwater, note the circular trench around the central peak islands.
- Elbow, Alberta – May
The position of the Elbow impact structure is illustrated by the superimposed circle in the background. The Gardiner Dam, under the wing of GO ZooM, is the largest embankment dam in Canada and one of the largest embankment dams in the world. Lake Diefenbaker is upstream. The dam rises 64 metres (209 feet) in height, is almost 5 km (3.1 mi) long and has a width of 1.5 km (0.93 mi) at its base with a volume of 65,000,000 cubic meters.
- Eagle Butte, Alberta – May – Shattercone
Shatter cone from the Eagle Butte impact structure, from fellow RASC member Mark Z.
- Pingualuit, North Quebec – May – Slickenside
Possible in situ slickenside formation on the Pingualuit Crater rim.
- Clearwater West, Quebec – May – Impact melt veins
The wall (light) and melt vein (dark) of West Clearwater Impact Structure-14-AR-016 in plane polarized light, showing pieces of the wall (plagioclase) being incorporated into the melt vein.
- Maple Creek (AKA – White Valley), Saskatchewan – May – age constrain <75 Ma
Maple Creek – the superimposed circle illustrates the position of the buried crater. This image, aimed looking west at the approximate point of impact, was taken from GO ZooM at approximately 2500 feet AGL.
- Cloud Creek, Wyoming – April
The wing of my bird GOZooM is pointing directly the center of the 7 km wide Cloud Creek structure. For scale, the distance l-r in the image is 4 Km.
- Glover Bluff, Wisconsin – April
Over the Glover Bluff impact structure.
- Victoria Island, California – April
I took this image in 1996 while flying over the Golden Gate Bridge, the peak of the bridge is just visible in the lower left. San Francisco is in the foreground and looking east, the position of the Victoria Island Structure is visible in the far distance of the image centre.
- Des Plaines, Illinois – April
I took this image of the Des Plaines Structure immediately after take-off from the Chicago O’Hare International Airport. We are over the south rim of the structure looking south.
- Howell Creek, British Columbia – April
Howell Creek Structure Geological map. (BC Ministry of Energy and Mines, 2001). The hypothesis – fossilized crater rim slump.
- Newporte, North Dakota – April
I took this image of the Newporte impact structure from about 5500 feet in my bird GOZooM. Ground zero of the impact is dead center in the image.
- Air&Space SMITHSONIAN – April
Crater exploration ESSAY
- Manson, Iowa – April
- Miami Florida Crater/Structure – March
This structure seems to be significantly <2km in diameter, yet it seems to be a complex crater with central peak.(image USGS)
- RASC – The Planetary Society – January
Crater exploration ESSAY
“We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.”
