Helicoptering Over Greenland

Early the next morning, our crew woke up for our typical Greenlandic breakfast of soft-boiled/scrambled eggs, bacon, greasy sausage, grapefruit, and an assortment of cereals. We ate in a hurry because we had an appointment to be at the airport early so we could get in as much time collecting samples with a helicopter as possible. The area around Narsarsuaq is vast and in order to get what we wanted in the time we had, we couldn't waste it on foot. We had three hours of rotor-time to work with, measured by the length of time from take-off to touch-down.

The weather was not perfect for us, and we were going to have to run our flight-plan by the pilot to see if what we wanted to do matched what his abilities and the weather would allow us. Our helicopter is only navigable by sight - so if the pilot can see where he wants to go, we can go there. The clouds were low in the morning, so we were not sure what exactly we would be able to do, but our pilot did not seem worried at all.
Our mode of transportation for the day. To the CHOPPER!!
Discussing our travel plans with the pilot.
If you've never been in a helicopter before, you need to ride in one as soon as you can! It's not to be missed, and even though you feel a bit more exposed than you are in an airplane, I never felt unsafe at all. Our pilot was incredibly professional and would not fly us anywhere he did not feel comfortable going. We headed up the fjord, passing one of the only "forests" in Greenland - it's actually a little research facility, but a forest nonetheless.

We got off to a good start, collecting a few samples in quick succession. But while we were just starting to gain elevation in one of the glacial valleys, snow started to fall, and not the fluffy kind. It was a pellet-type of snow that kind of bounced off of our jackets. We decided that while the clouds were low we would collect a few bedrock and boulder samples and hiked up a hill to pick some good specimens. The snow kept coming down harder, and we weren't sure if the pilot would be able to get us up to higher elevations to get more samples. Wouldn't you know, though, that by the time we got back to the helicopter, the snow stopped.
The pilot then, in about two minutes, took us from near sea-level to an elevation of over 1,000 meters (I think - it was very high up!).

It was awesome how the helicopter could just set down on any flat, tiny piece of rock. Our pilot was so smooth in setting it down, though a few times he had to try a few different spots because we were on weak snow or one of the skids was on top of a boulder or something of that nature. Inevitably, his piloting prowess shone through and we collected numerous samples from all different elevations.

The past week, it seems everyone in Narsarsuaq helped to build this bridge over the river. The center section was put in place a while ago, but the waters flowed over their banks and you couldn't get to the bridge, so they added extensions to it. We were the first people to actually use it. They did a good job and none of us fell in the river!

And then we were on top of the mountains!

Getting rock samples from high up in the mountains
After getting rock samples from the mountains, we flew up the valley for a few more sediment samples. Our ultimate destination were some streams directly coming out from glaciers coming off the ice sheet. To get there, we flew over a HUGE frozen lake that is just begging to catastrophically break and flood down into the valley. But then we got to the first glacier - much different that the ice sheet we saw up in Kangerlussuaq. Here the ice was incredibly thick and just kind of ended in a steep bulge. It was a little tricky finding sand-sized sediment here as the energy of the stream flowing out from the glacier this close to it is usually very high and the smaller sized sands are easily carried away. But we got what we came for and the pilot took us over to another tongue of the ice sheet. It's amazing how different each glacier we saw was completely different. This one was very steep, but it didn't bulge; rather, it came down in a sharp slope and ended abruptly. After bagging our sample here, we started flying to another glacier a good distance away. The pilot remarked how flat and huge the outwash terraces were and that they would be a pilot's dream to land on. He also liked that nature makes the perfect runway and that a contractor couldn't make a flatter surface.

As we took off for the next glacier, we flew over one of the most absolutely beautiful landscapes I have ever seen! During the melting season, the water from these two glaciers fills a valley, but is blocked at one end and a lake is formed. Large chunks of the glaciers calve off and float away into the lake. Later on the in the season, the lake will drain and the large icebergs will eventually be left behind to sit on the valley floor. We flew over this in the non-melt season, so the bergs were just sitting there! It was something none of us had ever seen before - even in photographs from textbooks! The other amazing thing about this landscape, which textbook photos allude to, is the color of the ice. You see in photos the bright blue, cerulean color of the ice and if you're like me, you think, "The ice can't be that blue." But in fact it is! Again, this is one of those times that photos just don't do reality justice!

Even though we had plenty of rotor-time left, our pilot was reaching the end of his shift and we had to get back to the airport. But we did stop and collect a few more samples - some very near to the mouth of another glacier some down a glacial valley right between humongous mountain peaks and some right near one of the most active calving-glaciers in southern Greenland.
Our next glacial destination. This one looks like it just spreads out over the landscape like a giant pancake!
The glacial margin. Here it is very thin and gently slopes up.

This valley was tucked right between some HUGE mountains!
And a fjord filled with icebergs!
We asked to see how much it would cost to keep the airport open a few more hours, and after hearing it would set us back $8,000 we decided to call it a day. But then we heard that someone else was paying to keep the airport open for other reasons, so we quickly refueled the copter and took off for another few hours to get a few remaining samples from high, unhikable, places. We didn't end up lucking out with the samples, but I got some great photos of the Narsarsuaq area from it!

Once we got back to the airport, even though we were flying around all day, we were exhausted!! We had used our helo-time very well and got to see so much of southern Greenland that other people only dream of seeing. And to have seen it all by air in a helicopter, continuously lifting off and setting down on the ground, hovering in mid-air - it could not have been any cooler or beautiful. The next few days were going to have a lot to live up to. And they would, in their own special way!

Narsarsuaq

The next morning came quickly and we repacked our bags to commercial-airline regulation-weight and caught a ride over to the breakfast cafeteria and airport terminal where we boarded our little Air Greenland Dash-7. We were going south to the settlement of Narsarsuaq, stopping for a layover in Nuuk, the capitol of Greenland. Along the way I was able to snap tons of photos of glaciers, the ice sheet, mountains, and fjords.

Narsarsuaq Airport!
Narsarsuaq is a sleepy little town of about 100 people, yet it has Greenland's second busiest commercial airport. The man sitting next to me on the plane pointed and said, "There's Narsarsuaq," as we approached. I saw the runway and tried to look at what he was pointing to. There were a few buildings next to the runway and I looked at him. He laughed and said, "Yes. That is it!" The town is a tiny, tiny little place on a flat strip of land on the edge of a huge fjord. Upon stepping out of the plane, I couldn't help but look up at the beautiful mountains surrounding me! Other than the ice sheet, this was the Greenland I was expecting to see: huge snow-capped mountains, calm blue fjords, colorful buildings, and a cool breeze. It was mid-afternoon, and after checking into our hotel and making arrangements for the next day's work, we schlepped it up to the middle of another vast outwash plain to collect one more sample.
All of the Greenlandic Ministers (political) were having a conference in the nearby town of Igaliku so the bus took them to the harbor, leaving us with all of our luggage. Luckily, there were no emergencies, so the ambulance drove our luggage over to the hotel for us!

The clouds danced around the mountains on the walk and while there was not much wildlife in this area, there were other things to see, including some really pretty, but small, bright pink flowers. And on a little mountian right in the town are some of the only actual trees in Greenland. Seedlings from Siberia, the Rockies, Alaska, and the Alps were planted here in the 1970-90s as part of an Arctic Arboretum. And just up the fjord there is an actual forest - though it is also planted for research purposes! And all over this part of Greenland are dozens of Viking establishments and ruins, including the very first Christian church built in North America, Erik the Red's original settlement, and the home of the first Episcopal Bishop. (More on all of those in the next few posts!)

After dinner (musk ox burger!), I took my own little hike up to the top of the little mountain in the arboretum to get some exercise and some good views of the surrounding landscape. It was beautiful and I got my first glimpse of the ice sheet down here in southern Greenland!
