Agree with Greg Davis. Lewis Baltz said "there is no history of photography", which is something I've been thinking about a lot recently. There is only a canon of photographers relevant to their own time periods and it's very easy to get caught up in the past. You might have to ask yourself why it is you relate so much to Ansel Adams and the classical photography - is it for subjective or formal reasons? You mention Stephen Shore who of course was part of the New Topographics, but his work is rooted in formalism. Everything he says about photography always comes back to his fascination with the ground glass and subtleties of composition. I absolutely agree that nearly every contemporary large format photographer is deeply influenced by Shore and it shows. Nadav Kander is one, but I love his work regardless, as his subjective concerns are unique. There's more humanity to Kander's work.
I've recently bought Uncommon Places by Shore and I looked through it probably five times the day it came in the post. His work is so rich and visually involving.
I also need to say that for the first few years of my photography, up until last year, I was only interested in traditional landscape work and predominantly British. All my pictures up until a year ago are concentrated on purely natural subject matter. I rapidly moved away from it upon the realisation that landscape photography, as a genre, is notable for being bound to convention - a collective way of seeing. Personal exploration is limited when you give yourself over to a tradition. I've also started to understand that the aversion to landscape photography in the art world comes down to this very fact that it's a world unto itself. It plays by its own rules, which for me, felt like a straightjacket. A niche within a niche as they say. Photographers such as Darren Almond, Thomas Joshua Cooper and John Blakemore who work in the landscape, have done so with a personal way of seeing. There isn't a near-far or 80/20 composition to be seen. Their work is notable for its personal expression and the art world likes it better for this reason, which is no bad thing. Maybe you could have a look at their work as a starting point for broadening your horizons... so to speak.
