I remember reading a series of young adult (at the time it was called juvenile) science fiction novels in the 1990s with a Christian slant (characters were occasionally seen praying, and so on).
In one of the books (I think it was the third in the series?), one of the characters is involved in an experiment in Colorado that goes horribly awry, creating a column of energy where time inside is frozen. The column also shifts the Earth's axis, wreaking havoc across the globe. One of the other characters essentially has to go into the column and shut the experiment down, causing time to reset to the moment when the column first appeared.
Any help tracking this series down would be appreciated.
