George, you know that mass works. In Arizona adobe was common for low elevation. It relied on diurnal temperature variations to stay comfortable. Too many cold days and it was real uncomfortable. Then the mass was working against you. Summers, like yours, with high diurnal swings worked well.
Hait's basic plan called for a dirt mass 20 feet beyond the house perimeter with the walls mostly buried. Two feet of overhead, under-umbrella dirt. The 20 feet is what Hait measured heat to move in his Missoula fill in 6 months. The mass under the house is part of the house also, down that same 20 feet.
Fills, and substrate vary. I account for that, but it's rarely critical.
The small PAHS ΔT between mass and indoor temp means a large area of surface contact is necessary for adequate heat movement. The first time I modeled a house with a standard basement (most of these resemble a walkout basement with no house on top) I was surprised at how well a basement functioned. Shouldn't have been surprised, but I was.
In France, the current movement is to use curvilinear thinshell concrete combined with PAHS. There's a venerated tradition of thinshell concrete Maison Bulles, bubble houses. Unbelievably uncomfortable winter and summer. PAHS solves that.
Two years ago a young Frenchman I helped with PAHS for his thinshell concrete in the shape of a nautilus talked me into a 9 day road trip to visit these famous houses. He knew everybody. Take a peek at one of the most famous.

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
