All of my landscape photos are taken on medium format kit. I use a carbon manfrotto tripod and ballhead.
I use a Pentax 67II system with 55, 75, 105, 135 macro and 300mm lenses. This is my main camera system, which is carried in a Lowepro Dryzone sac most of the time.
For longer / mountain walks I take only the 75mm lens, stored in a Lowepro toploader padded case inside my adapted Macpac climbing sac (extra straps + buckles to carry tripod in the most secure and stable way).
I also use a Fotoman 617 panoramic with 150 lens - fits into a small Lowepro mini rucsac with spotmeter etc. On shorter trips this is carried, on longer / mountain trips it fits inside my Macpac sac.
If weight is a real issue, then all my normal gear is not used - I use a Fuji GA645zi and very lightweight small velbon carbon tripod and ballhead. I love the 67 format however and fancy giving the Mamiya 711 and stanard / wide lens a go (funds won't allow this for some time!) just for mountain trips. See this thread:
(there was a url link here which no longer exists)
Over the years I've found it a constant balancing act trying to keep medium format kit and the outdoor kit needed for mountain trips at a manageable level...!
Cheers,

PS - the picture you posted looks fine mountain terrain...
