My mind is brimming with  wondrous exclamations of the sights and sounds of our experiences of the last week. And today was such a pinnacle.
We got an  early start as we motored out of the Chilean fjord with no wind, but the  tide was in our favour giving us a good over-ground speed. After about  20 nautical miles south, we reached the treacherous passage through a  shallow and rock fringed bay where we encountered our first "bergy  bits"!
What are bergy bits?? Bergy bits is a nickname  for iceberg pieces that have broken free from a glacier. Some were  floating by, some were washed ashore by tidal forces, and some were  large enough to be stationary - sitting on the ocean floor at low tide  as the currents flowed past.
Careful navigation required (only 10% exposed above water surface)
Jordan  at the helm was constantly dodging these pieces of ice, the very large  and the very small. Bergy bits were everywhere! He didn't want to hit  even the smallest because they are quite literally as hard as rocks.
This  area of the bay we found to be confusing as the markers did not make  sense to us. "Red Right Return" (a sailing term) did not seem to apply  here. The tide was also lower than what we had predicted according to  the nearest tide table and we hit bottom twice. But Jordan eventually  meandered his way through the markers, low tide shallows, and scads of  bergy bits before finding the river entrance of Rio Tempanos. Not a  passage that we would recommend for the feint of heart!
Traversing  up the freshwater river was easier than through the bay as the river  was deeper and there was only one direction to go but Jordan still had  to dodge many bergy bits. Then we finally came to the lake, called Laguna  San Rafael, about 4 miles across and strewn with icebergs and bergy  bits.

The 
ventisquero  (glacier) here was difficult to spot at first because of the low clouds  and hazy day. We continued to make our way towards it and then,  finally, there it was! Absolutely breathtaking!!
But wait...what's that...the engine suddenly quit! Jordan was  puzzled because plugged filters had previously given warning signs in  advance, but this time it was a sudden stop. We very slowly drifted towards Ventisquero San Rafael as Jordan changed the 3 fuel filters and  bled the lines successfully in about an hour. I was feeling a little bit  anxious but I spent the time taking more photos of the glacier and  pieces that were floating by and never hitting us.
We had made VHF contact with 
Patagonia Express (a tourist  catamaran) and they were standing by on VHF in case our engine wouldn't  start. But all was well and we soon motored over closer to the face of  the glacier.
Still 1/2 km away from the glacier
Orca IV, another sailboat, had also arrived and we agreed to swap photos of boats with the glacier as a backdrop. Here is

Can you spot the zodiac dinghy in the photo below? Just an indication of the size of this glacier...
In  total, we spent hours taking photos (over 500!) and just peering at  this monstrous beauty. Listening to the rumble, creaks, and groans and  watching the calving - pieces breaking away and crashing into the lake.  Spectacular! The colours of the glacier and the bergy bits are  indescribable...intense blues, pale blues, greenish blues, snowy white,  glassy clear.
Incredible colours in the ice
We celebrated this momentous occasion  with, of course, Chilean Pisco Sours 
chilled with ancient glacier ice  that Jordan scooped from the lake!
Tasty but VERY hard ice to break
Now if you  know me, you know I'm a fair-weather gal. But I wanted to do this  passage as much as Jordan for the excitement of seeing a glacier before  they're all gone. But we were both surprised that we only had this one  chilly day. The rest of the time, we were actually over-dressed and too  warm. I was even taking photos of the glacier on 
Sea Turtle's deck in  bare feet and too enthralled to remove my windbreaker!
It was hard to tear ourselves away but finally at 16:30 we had to  leave so the tide would be running with us. The passage leaving was  much easier as most bergy bits had flowed back into the lake  with the pressure of a rising tide in the bay downstream and some had also melted considerably.
We soon came back to near our first anchorage at Estero Elefantes  (S46°24.315' W073°47.867') that we had left early this morning and  settled in for another windy night. 
Orca IV also anchored nearby.
