Please help ID a tree at Spicer Garden, Nakusp, BC

Hi,
My sister took a picture of a tree at Spicer Garden at Nakusp, BC. I'm stumped by the leaves and the little curling tendrils. I thought it might be some type of Oak but the leaves are curled and I can't see them properly. Could anyone help with this? Thanks! Picture is attached.

 

Looks like a Contorted hazelnut tree, Corylus avellana 'Contorta'.
Lucky the eastern filbert blight hasn't affected it if it is.

 

Thanks, I'll look them up. I sure hope that one doesn't get blight because it's so beautiful.

 

Aka 'Harry Lauder's Walking Stick'.

 

yes, I agree, a hazelnut (aka Filbert) - the non-contorted version is a huge commercial crop in the Pac NW of Oregon (SW of Portland, OR) ---- some used to be out near Agassiz - Rosedale in BC too - not sure if those farms are still out there.

I think some might grow wild - not sure if they are native of "volunteers" ... ie spread by wildlife.e
