People should go to the works and experience them. Because just having an idea or picture in mind is absolutely not the experience that's necessary. Even just landing in Albuquerque or Salt Lake City or Las Vegas was immediately part of the experience. And then you'd get in a car from the airport and take these very long trips - in Michael Heizer's case, it was three hours by car to get to his work. And then there's walking around and into the piece and seeing it from different angles. The kinetic experience of being a part of it physically was very important for me.

People tend to view land art as something that happened at a certain historical moment - like minimal art, which I was also very much involved with. But it still goes on. It's very much alive.

Quite honestly, even as a woman dealer, I really wasn't interested in masculinity or femininity as such. What was important to me was the value of the work itself. If a woman had come along, somebody like Lee Bontecou or Louise Nevelson, and said, "I'm working on the land," I would have gone to see it.

The gallery closed its doors in 1971. I could no longer psychologically handle the needs of 12 artists. I cared about all of them, and what was happening with their careers. I'm just not a person who can do that indefinitely. And tax-wise I was concerned because they gallery wasn't making money; it was losing money.

I enjoyed cross-country road trips. And I found the work challenging because it was art that existed on the land rather than mere concepts in a gallery or photographic documentation, or any of the paraphernalia that can be used to indicate that. The art was on the land.

I think the four land artists I showed all worked within a few years of each other. And they were standard bearers, I suppose, for land art. They each did very separate things. Apparently, later in California, a lot of artists started working in that medium and there was something of a rush of earthworks. But I wasn't involved with that.

There's a definite connection in terms of objects at hand - dealing with objects or material at hand. Pop art was very much enamored with popular imagery, and popular imagery was of course available and at hand. And land art was also using what was at hand.
