That39。s how our shipboard naturalist John Fonseca describes the slushy ice that the Silver Explorer is plowing through as we enter Greenland39。s Prince Christian Sound, named after a longago Danish royal who became King Christian VIII. In the distance, the water surface is a smooth sheet of darkgreen jade under the overcast sky. The cruise ship suddenly feels larger as we slip into the narrow passage of the sound. Bigger and bigger chunks of sea ice float by, like huge gobs of whipped cream dropped on the surface by some quirky Norse god. The sculpted forms pass so close, it39。s tempting to stretch out a finger for a poke and a taste. At its base, the rocky shore on each side is often green with moss and lichen. But it quickly bees less hospitable and even forbidding, its glacierscarred face climbing steeply until disappearing into low, filmy clouds. Some patches of ice have lingered since last winter, though the August sun is converting the most exposed into waterfalls that trickle merrily into the brilliant sea. Leaning on the observation deck at the ship39。s Level 6, Fonseca tells us we39。re looking at rocks that are 2 billion years old. Some of the harsh striations have been dated to the tectonic plate shifts of 65 million years ago that broke up the Earth39。s landmass into the continents we know today. There are about 50 passengers on board, most huddled among the rails at 8 am in the bright red parkas provided by the Silversea cruise line. The air temperature is 9 C－ the water temperature is12 C, expedition leader Stefan Kredel announces on a loudspeaker, just in case anybody is planning to strip off for a morning swim. Our luxury vessel is small as cruise ships go. American TV39。s Love Boat may have had athousand cabins, sports courts and a pooland there are massive ships like that in the nextharbor with a big herd of passengers but things are more intimate Explorer39。s relative pettiness is key to our itinerary. At the moment, we are cruising overa channel 240 meters deep, but yesterday, winding through Skoldungen Fjord, we hadscooted over depths as shallow as 69 meters. You can39。t do that on the QEII. That flexibility is essential to the expedition ships and cruises offered by Silversea. Whilethe line offers the more traditional cruises focused on shipboard entertainment and portcalls for shopping and nightlife, the expedition variety is targeted at more adventuroussouls.We started these as outings to more outofthe way places, specifically the Arctic and theAntarctic, for active travelers who wanted to learn about and explore wilder places upclose,says parking your butt in a deck chair is your idea of a deluxe cruise, you39。re on the wrong day, Silver Explorer works its way as close to shore as possible before droppinganchor. Then we pull on our waterproof pants, jackets and boots, and climb singlefile intoZodiacs－ the big, motorized rubber rafts that will take us to the day39。s adventure. Yesterday, that was a 90minute foray around Thrym Glacier. Today, we zip ashore to visit the indigenous village of Nanortalik, where small oilheated houses painted in bright colors dot a mountain valley that clings to summer39。s last yellow wildflowers. We explore an outdoor museum, watch a kayak demonstration at a traditional hunting camp, enjoy an 20 Inuit choir performance in the church, and enjoy coffee and a folk dancing at the local culture center. Nanortalik means place of polar bears in the local Inuit language, but a fanged ivory skull in the museum is the closest we39。ll e to seeing this fearsome creature on this voyage around southern Greenland. Tomorrow we39。re promised a landing near two thermal pools with a view of passing icebergs. Those swimming suits we packed will be used after all. Each day, there is at least one lecture by an expert－ a geologist, birder, Viking scholar, botanist, anthropologist or marine biologist. These informal talks are fortably spaced between gourmet meals and freeflowing wine and spirits, all of which can be enjoyed in the collegiality of the restaurant or in the cozy privacy of yo
