If history repeats itself, a diverse group of climbers will make the trip to the Ibex Valley on Sunday for an annual bouldering festival.

This will be the sixth annual Ibex Bouldering Festival and it will run all-day, starting at 9 a.m.

Three different circuit difficulties will keep all participants entertained from the most experienced boulders to those trying it for the very first time.

"Every year it's bigger and more people come," said Ethan Allen, an organizer of the Ibex Bouldering Festival. "It's been just such an amazing time and we have always had good weather and a good turnout.

"We know it's going to be the same this year, except even bigger and better than ever."

The festival has always been put on as a family event and primarily non-competitive. While bouldering is the primary activity, there will also be other types of entertainment, including slacklining, highlining and live music.

There will be a time period for a climber to go on their circuit sheet and try to complete as many problems as they can.

Each circuit might have 10 or 12 problems, which range in difficulty.

Some format changes have also been made for this year's event, which Allen said should benefit the festival.

In previous years, a group leader was used and participants were separated accordingly to a certain level.

However, the 2009 version will be more independent-themed. After a circuit sheet has been given out, an individual will then around to different areas, trying to complete as many problems as he or she can. Instructors will be around at the different areas to facilitate, Allen said.

The three circuit difficulties include beginner, intermediate and advanced.

Another new aspect to the festival is a dyno competition, which will be optional for those registered on Sunday.

A dyno is a dynamic movement, essentially jumping with your arms and legs to see how far you can go.

Allen said an artificial wall will be used for the competition and participants will have three tries to "dyno" a certain distance. If successful an individual will then move onto the next round.

Prizes will be given out in a draw for both the dyno competition and those who tackle one or more of the circuits.

Allen said organizers are also hoping to screen a short bouldering video put together by his sister, Sierra, in the evening.

Sierra is no stranger to the sport and made history this past July after she completed the most difficult bouldering project in the Ibex Valley (and quite possibly the whole Yukon). The project was named Puravida and has had people trying to complete it for more than a decade.

Allen said he hopes she will demo it again on Sunday, adding he plans on attempting it himself.

A climbing and bouldering task is referred to as a project until someone has successfully completed it.

In addition to the possible short film screening, a professional photographer, who specializes in climbing, is coming up from southern California and will put on a slide show of his past work.

Allen encourages anyone who is interested to come out on Sunday.

"If you are sitting on the fence and thinking maybe I could do this, absolutely you can," he said. "I don't think you will be disappointed if you come out and give it a try."

He said the indoor climbing skills transfer over well, but added there are some big differences between the two.

One of the central differences is the indoor climbers tend to focus a lot on using arm strength because of having the option of putting your feet in big foot holds.

Allen said the Ibex Valley has lots of rock that doesn't have as much room for feet, so have to use your feet.

"It's really important to use your feet," he said. "That's definitely an important thing to keep in mind."

Registration can be done on Sunday at the Ibex Valley. Signs will be posted along the way. The cost to register is $10 for adults and $5 for kids under 12.
