Noticed something weird at the Hoover Dam visitors center last month

I took a tour there on my way through Nevada, and the guide kept skipping over the whole 1935 construction story, like it didn't matter. But the displays show a ton of internal concrete temps that supposedly hit 150 degrees, and they poured it all in one go? That math never added up to me. The guide got real quiet when I asked about the cooling pipes, just said 'company records lost' and moved us along. Has anyone else gotten that same brush-off on the dam tours, or was it just my guide?

Cooling pipes, concrete temps, missing records. Sounds like the tour guide and I have the same strategy when things get uncomfortable. I just nod and pretend I didn't hear the question.
