The Tertiary Period (65.5 to 2.588Ma) is the informal name for the geological period that followed the K-T extinction event. So the K-T event happened before the Tertiary. In fact "K-T" is actually short for Cretaceous-Tertiary as it marked the end of the Cretaceous and the start of the Tertiary.The lower tertiary is more formally known as the Paleogene Period(65.5 - 23.03 Ma) and the upper Tertiary is more formally known as the Neogene Period(23.03 - 2.588Ma).
A boundary is a borderline, a separation between two things or the edge of something. Tertiary means third. In this case the 'Tertiary Boundary' has a geological meaning. It is an horizon in the Earth's rock sequence that marks the end of the 'Tertiary Period' at the end of the 'Cretaceous' and the begiining of the 'Quaternary Period' - a point in time in Earth's history some 65.5 million years ago. It is also the time when the Dinosaurs became extinct.
Earth's geography changed dramatically between the beginning and the end of the Tertiary. I could give you a long winded description, but I think you would prefer maps. Under "Related Links" there will be a map for the early Tertiary (called the Paleogene), and one for the later Tertiary (Neogene). P.S. The Tertiary began 65.5 million years ago and ended 2.6 million years ago.
During the Tertiary period, a variety of rocks were formed, including sandstone, shale, limestone, and volcanic rocks such as basalt and andesite. The Tertiary period was characterized by changes in climate and tectonic activity, leading to the formation of diverse rock types in different environments.

All mammals present today are example of tertiary period mammals as we are living in tertiary period .
K = Cretaceous (C is used for another era already) T = Tertiary

The Tertiary Era.
The "tertiary period" is not a place you can go to. It is a time period - in the remote past of Earth. Since it is in the past, you can't go there.
The k-t extinction was ~65million years ago and marks the transition from the Cretaceous to the Tertiary period.
