Historic Glacial Confluence
This is the site of confluence of the former glaciers Vernagtferner and Hintereisferner, two of the most (and longest) studied glaciers in the world. It is the site (at ~2200m) where several times over the past thousand years the ice of the Vernagtferner would pile up to form a massive dam, 150-200m tall, which caused a semi-permanent ice lake to form in the Rofen/Hintereis valley above (the one visible from ~7 seconds). Many times this lake would get up to …
The US Federal Reserve held interest rates steady for the second time this year,
a widely expected move amid turmoil in the Middle East and rising energy prices.
Fed officials faced a confluence of issues to consider in their meeting this week:
soaring oil and gas prices,
fluctuating inflation that still remains above the Fed’s target of 2%,
and a weakened job market that unexpectedly saw 92,000 losses last month.

Today is a twofer of #CanadaRivers as we countdown the longest rivers in Canada.
#23 is the Red River which flows for 890 km, originating at the confluence of the Bois de Sioux and Otter Tail rivers between the U.S. states of Minnesota and North Dakota, flowing northward through the Red River Valley and continuing into Manitoba. It empties into Lake Winnipeg, whose waters join the Nelson River and ultimately flow into Hudson Bay. The river only falls 70 metres over it's length, so there are no hydroelectric opportunities, but because it drains a large watershed of 287,500 km2 it experiences significant spring volumes. This has led to calamitous (love that word) floods plaguing southern Manitoba for centuries. Flood canals and ice cutting (physical removal of large blocks every spring) have mitigated the risks but not eliminated them.

Good Morning #Canada
We're now getting to the big ones... as we break into the top 10 in #CanadaRivers. The South Saskatchewan River is #10, beginning at the confluence of the Bow and Oldman Rivers in southern Alberta and ends at the Saskatchewan River Forks, the confluence of the South and North Saskatchewan Rivers which then becomes the Saskatchewan River. Flowing for 1,392 km it drains a watershed of 146,100 km2, 1,800 of which are in Montana, USA.
Major dams were constructed on the river to prevent flooding, for reservoirs, irrigation, and for hydroelectric power. The South Saskatchewan provides approximately 19% of the hydro-electricity generated by SaskPower. A 2009 WWF Canada report analysed the river flow on ten Canadian rivers & found the South Saskatchewan River was most at risk. Climate change, agricultural & urban infrastructure water use, and dams producing hydroelectricity, have all combined to reduce the flow of the river by 70%.
