Peter,
Oops! I should have said 12h 21m 24s MDT. But I realize now that 97º36'W would be in Mountain Time (just barely) if the time zones were actually 15º wide. It is, in fact, in Central Time (assuming a U.S. latitude), so 13h 21m 24s CDT is correct.

Steve,
I know you asked about using the printed almanac. Since others have already answered that, here is my answer using Excel; varying input UT until Sun’s GHA matches your longitude gives: UT = 18h 21m 24s, which is 13h 21m 24s Central Daylight Time, so we agree! Please see attachments - this trial and error procedure took about half a minute.
