Evaluation of Evidence vs. Proposals

Table 99 summarizes how well each of nine proposals explains the many strange features of the Grand Canyon. Each column corresponds to a proposal, and each row represents evidence requiring an explanation. A green circle means that, in my opinion, the column’s proposal reasonably explains that row’s diagnostic detail. Yellow and red circles indicate moderate and serious problems, respectively. Numbers in Table 99 refer to additional information below.

Readers should make their own judgments and independently assess each proposal’s plausibility. For example, if you feel that a detail or proposal has been omitted or misstated, modify the table. This approach focuses future discussions on areas of critical disagreement. It also helps keep all details and competing views in mind, encouraging balance and thoroughness. Sometimes a disagreement over one detail becomes moot when one recognizes other facts that oppose a proposal. Often, when a theory is presented, only the details supporting it and opposing competing views are mentioned. Table 99 contrasts the best-known published proposals with all the "Evidence Requiring an Explanation" beginning on page 219.
