Snow White Blacknoses?

These photos were contributed to the WOVEMBER 2012 competition by Ericka Olsen Stefano… WOVEMBER wonders if they are Snow White Blacknoses, as featured in this documentary film, and what their wool is like? Can anyone enlighten us?

‘I’m sending in three photos of sheep in Switzerland. The unusual looking breed is from the upper Valais, and has been making a comeback’. – Ericka Olsen Stefano
