Most Ancient Life on Earth

They are called "thrombolites" and they were 2 km from our B&B in Flower's Cove.  They are a microbial community that we now see as rounded rock structures.  But they really look 'organic', if that word can be used for rocks.  They date as far back as 3.5 billion years ago (yes that's 3.5E9) and represent the first forms of life on this planet.  Apparently they are quite rare (the only other known site is in Australia) so it is rather amazing that this is not a nationally protected site.

Since our Labrador sojourn was abbreviated, this has given us time to explore Newfoundland at a more casual pace.  Loving the most northerly region, we headed east again on the Viking Trail, skipping L'anse aux Meadows and heading to St. Anthony's.  St. Anthony's is a 'real' place with facilities like a hospital and, okay, a Tim Hortons which was our first stop.  Earlier when at Port au Choix, we had bought a book called 'Our Seniors', in which the eldest people were interviewed about their lives in Port au Choix.  This turned out to be a fascinating tale of pre-confederation times with much poverty, many children who died, deaths by drowning and tuburculosis.  They made clothes out of flower sacks.  During the war, the German U-boats were picking off fishing vessels in the Strait of Belle Isle regularly.  In this book, St. Anthony's figured repeatedly because it had the only doctor (later doctors).   Dr. Grenfell (there is a Grenfell College associated

But, sadly, the Ford Fusion wasn't up to the challenge. We must have done something right in our lives because just as we pulled in to Mary's Harbour, the car started to beep indicating low tire pressure and when we stopped in front of the motel the left rear tire was well and truly flat.  At least it didn't happen in the middle of nowhere, though there were actually quite a few road crews work
