Under Mount Tucker in British Columbia's Glacier National Park, a sprawling system of uncharted caves offers a group of unlikely explorers a chance to venture into the unknown.
These are not the cartographers of yore. Today, the Cabots, Cartiers and de Champlains mapping the wilds of Canada have been replaced with adventurers of a more amateur sort, armed with time to kill and money to burn.
The nine-member expedition, which includes an accountant and teacher as well as scientists and cave guides, is planning to head into the network of caves in October.
The explorers are all volunteers and trips such as theirs are on the rise, the Royal Canadian Geographical Society says.
The Raspberry Rising trip — named after the cave system's hidden entrance — is one of several the Society says they have provided funding to this year through their expeditions program.
"The last probably two to four years, we're seeing more applications coming in, and we're seeing better applications coming in," says Michael Schmidt, an explorer based in North Saanich, B.C. and the co-chair of the expeditions program. A separate program funds scientific research.
The program has seen applicants double from 2011, according to John Geiger, the president of the RCGS.
That year, there were seven seriously considered applicants, he says. For the 2012 and 2013 programs, there were 14.
The RCGS grants range from $500 to $15,000 for expeditions. The grants go largely to experienced amateurs, for trips that straddle the line between field-work and adventure travel. The expeditions must combine education and outreach — including social media campaigns — with physical challenge and remote locales.
"Ten years ago somebody might have said, well look, the whole country's been explored, what else is there to do?" Schmidt says. "And you know we keep seeing people who are going out within our expeditions program, and they're kind of poking into places that either haven't been or have rarely been visited."
Modern explorers bring high-tech equipment underground and use satellite technology to tweet from ice-floes. Expeditions also consider First Nations' histories before claiming to have mapped or documented a mountain or island for the first time.
In Nunavut, a two-month expedition is currently underway to paddle across Baffin Island in kayaks the team built using traditional Inuit methods. The four-person team includes professional explorers, a doctor and a professional kayaker.
Last week, a McMaster PhD student named Adam Shoalts began a solo canoe expedition to northern Quebec and Ontario, where he says he will map several waterfalls he claims to have discovered last year.
This fall, the group heading underground will begin squeezing through tight passageways, scuba diving through tunnels of melt water, and climbing waterfalls frozen into slicks of ice in order to map the system for the first time. And those are just the sections of the cave they have already seen.
"With the underground and cave exploration, you do not know what's around the corner, what's beyond your head lamp. You can only guess," says Nicholaus Vieira, a self-described "cave bum" who conducts cave tours and lives in Canmore, Alta.
The Raspberry Rising expedition will be risky, time consuming and expensive. Tens of thousands of dollars have already been spent and the project could take years.
"We do this for fun," Vieira says. "That's the messed up part."
Geiger says exploration has generally flourished in times of wealth and stability. And in a largely urban, plugged-in, stable society, it makes sense that people crave adventure, he says.
"We're comfortable, we're safe, we're wealthy, we're well educated," Geiger says.
"And so we're in an incredibly comfortable place in the context of human evolutionary history. But there's something that makes us want to go further, and to experience risk, and to test ourselves."
Canada has long been a strong country for explorers, says Jason Schoonover, an ethnographer and spokesman for the Canadian chapter of the Explorer's Club.
The New York-based Club, which has included Neil Armstrong, Sir Edmund Hillary and Tenzing Norgay among its members, has given its highest medal to Canadians the last three years.
This year, deep-sea explorer James Cameron, better known as the director of Titanic, received the Explorer's Medal for his solo dive into the Mariana Trench.
In 2012, the award went to Alberta-based paleontologist Phil Currie, and the year before it was presented to ethnographer Wade Davis, who is from B.C.
Membership to the Club — which requires sponsorship by current members and evidence of scientific field work — has been growing yearly, Schoonover says.
And expeditions within Canada are fuelled by increasing interest in the North.
"There's a lot more focus on the Arctic right now. And it's warming up, which is making it much more physically feasible to do this kind of work."

Fossil Forests on Ellesmere Island, Nunavut
Millions of years ago, about 55 million years ago, the fossil forest on Axel Heiberg Island was a wetland forest. Temperatures hovered around the 18-degree Celsius mark, not the -10 degrees of today. Silt-rich flood waters preserved the flora - palm trees, dawn redwoods, bald cypress and cycads - perfectly. While this photo doesn't depict the fossilized forest, we hope it ignites a curiosity in seeing the North. And should you have a rare photo of the fossil forest, please do send it along and we will be happy to publish it.
We share Niagara Falls with the USA, two-thirds on the Canadian side of the border (the Canadian Horseshoe Falls) and one-third on the American side (the American Falls). The Horseshoe Falls are 57 metres high and 168,000 cubic metres of water crash over the crestline every minute during the peak daytime hours. Favourite ways of navigating the Falls have included barrel, tight-rope, and, less successfully, by kayak and jetski. Today, visitors can experience the Falls by taking a trip on the Maid of the Mist or the Whirlpool Jet boat.
Niagara Falls, Ontario, Canada
At the outflow of Lake Erie into Lake Ontario and a 90 minute drive from Toronto, the natural wonder of Niagara Falls is one of the most famous places on earth, and about half of it lies in Canada. With its thunderous curtain of cascading waters that you can see from beside, on top or even from underneath, the incredible uniqueness and panoramic beauty of Niagara Falls are two of the main reasons why most visitors hop aboard the Maid of the Mist boat to ride right up close to the action.
Scientists know that the Northern Lights (or Aurora Borealis) is caused by particles flung around the solar system and attracted to the magnetic field around the poles. However, the otherwordly darts of light - green, pink, red and gold - have been seen as omens of good or evil by the first peoples who lived in these extreme latitudes. Yellowknife in the fall and winter is best place to experience Mother Nature's light show.
Northern Lights - Time-lapse - Southern Ontario, Canada Oct 24, 2011
My son Mark (MarkFreeman408 on YouTube) filmed this time-lapse vid of the Northern Lights (Aurora Borealis) from our back deck last night, near London, ON, Canada. They were seen into the USA as far south as Atlanta, GA & Memphis, TN. This winter of 2011/2012 is expected to be a peak time period for the Northern Lights. The red colour seen is the most rarest of all the colours.

Singing Sands, Prince Edward Island
As you walk along the white sand beach at Basin Head listen carefully to what the sand is saying. It sings, or some say it squeaks. Perhaps it's due to the shape of the quartz sand that makes up the beach.

Bay of Fundy, New Brunswick
Renowned for its high tidal range and rivalled only by Ungava Bay in northern Quebec and the Severn Estuary in the United Kingdom. The Hopewell Rocks formation earns it a place in this Canadian Wonders list. The Hopewell Rocks on the edge of Shepody Bay have been carved into "flowerpot" shapes by the tides. At low tide you can walk to them. You'll need a kayak to see them at high tide.

Manicouagan Crater, Quebec
Is the Manicouagan Crater a legacy of the impact that may have spelled the end of some species 210 million years ago? The fifth-largest crater in the world has multiple rings, however the inner ring, occupied by a lake, shows up most clearly in satellite images, sapphire-blue water piercing the green land. René-Levasseur Island occupies the centre of Lake Manicouagan, named for the engineer who created the Manicouagan Reservoir.
