Snow-shoeing / Hiking a mountain

Hi folks.

Any recommendations on where to find a calorie estimator for snowshoeing/hiking a mountain?

I see most out there assume snow-shoeing is cross country, or hiking a mountain is without snowshoes, for example, but nothing combing the two.

I do know that adding snow shoes increases the calorie burn significantly, so trying to get an accurate estimate.

We did 3 hour hike up about 4000 feet, then an hour down.

thanks!
